Consider this solution for the Olivia-Kiara: I looked at it this way: Since olivia walks 3mph faster than kiara, she would need more than an hour to catch up. One hour = 3 miles less. Then 1 mile would be left, and since it took 60 minutes for 3 miles, she would need 60/3 = 20 minutes for the remaining 1 to catch up. So 60 + 20 = 80.
Very efficient. My formula Kiaira 5(time) + 0(starting point) =Olivia 8(time) -4(starting 4 miles behind Time =4/3hr or 80mins. I like your way better.
@2:15 - for the first problem the alternative is to calculate it first by percentage, utilities is 40%, Heating is 15% more = 46% Remaining is 14% 14% of 1500 = 210
The olivia and kiara question Their relative velocity, v is 8 - 5 = 3mph since they are moving in the same direction. Therefore the time difference, t = d/v =4/3 hrs 4/3 x 60 mins = 80 mins option D

Chech how much each one travels in 70 minutes and you'll figure out the result is 80. (70 min / 60 min) x 8 mph- 4 miles = 5.33 miles and (70/60) ^ 5 = 5.83. Replace 70 si 80 minutes and you get the result. Or even simpler 5 mph * X hrs = 8 mph * X hrs - 4 miles, where X is the time when Olivia am Kiara reach the same point. X = 4/3 hours or 80 mins
I think triangle question answer is 7 because if we consider rest all numbers pairs those are counting to 10 ex:- 8, 2 (8+2= 10) 4,6 (4+6= 10) 3 , missing (3+X=10-->> X=10-3--> 7) Hence 7 would be the right answer.
First question alternate answer:: 15% of 40% = 6% (1.5*4) so we have 46%+40%=86%. Remainer is 14% *1500 = 210 (150 + 15*4 ). Notice the reccurance of 15*4. Question at 12:00 it is much easier to multiply the extra 260*4=1040 which we know equals the single studet rent for 5.
Four days before Monday: Is it Thursday or Friday? If I start counting from Tuesday, 4 days before Monday is "Friday" (video 29:17 min). But video says Thursday.
For 3:28 With the given data Olivia walks 8mph which is equivalent of 7.5 mins/mile and Kiara walks 12mins/mile. For Olivia 80 mins olivia can reach 10.67 miles (80/7.5) and Kiara can reach 6.67miles (80/12). Since Olivia walks 4 miles behind, so the computation will be 10.67miles minus 4 miles = 6.67 miles which is equivalent to travel distance of Kiara after 80 mins of walking. So the anwer is D. 80 mins
Since all the possible answers are in MINUTES, you need break down the miles per hour for Kiara and Olivia into the common element of MINUTES per hour. For Kiara, divide 5 (mph) by 60 (60 minutes in an hour) which gives you 0.083 miles per minute. For Olivia, 8 (mph) divided by 60 (60 minutes in an hour) which gives you 0.133 miles per minute. Now start multiplying by each possible answer minute amounts to find when they match after subtracting 4 from Olivia's number (she started 4 miles behind). The answer will be "D" as 80x0.083 = 80x0.133-4 (the answer for both is 6.64). I hope this helps.
I looked at it this way: Since olivia walks 3mph faster than kiara, she would need mpre than an hour to catch up. One hour = 3 miles less. Then 1 mile would be left, and since it took 60 minutes for 3 miles, she would need 60/3 = 20 minutes for the remaining 1 to catch up. So 60 + 20 = 80.
12÷2(3-1) I would argue that 2(3-1) is a factored term and you would solve that first then divide. You would redistribute the 2 into the (3-1) to get 12 ÷ (6-2) => 12 ÷ 4 => 3
I agree with this as the 2 is right next to the parenthesis. If there was an operation symbol between the 2 and the parenthesis the approach he used would work.

Rent question would be probably easier to think about without formulas : if everyone is paying $260 extra and there are four of them that means they are paying $1040 extra and since everyone is paying the same amount for 5 rooms, the total is $5200
Question of guessing the missing number 18*3 = 27 12*4=12 22*8=32 12*9=? has wrong options it should be 27 since as per logic all double digit numbers are added together and then multiplied, 18*3-->(1+8)*3--> 27 if this is the logic then either last option should be 22*9 which would be 36 as suggested in the answer in the video please correct me if I am wrong.
Olivia - Kiara Question: One correction would be: Olivia catches up to Kiara not otherwise. Solution: Lets assume they take time T to meet/catchup and in doing this they cover a total distance of Y. Since Kiara had a head start of 4 miles, she covered Y in time T by, 5*T+4=Y Olivia covers Y by, 8*T=Y, equating both, 5T+4=8T-->T=4/3 hr or 4*60/3 mins=80 mins
For this one 18*3 = 27 12*4=12 22*8=32 12*9=? Here, in the question it was 12*9, but when the puzzle was solved, it was 13*9, that's why the answer is 36.
For the rent problem. multiply 260*4, the total amount the reaming for have to pay=1040, which is 1/5 of the original rent. take 1040*5 =5200. That is the total rent. on the series of numbers how can you possible know to mutiply each of the two digit number by the singe digit and add them up. This is pure evil.

that one calculating rent... you wont have enough time to break down the entire problem like that. Instead, take the 260 and just make it 200. 200 x 4 = 800. That's each persons contribution. 800 x 5 = 4000 which is higher than any answer BUT A) 5200 so that is the answer. If you wanted to confirm, you can add the 60 back in as (60 x 4) x 5 which is 1200, or 5200 total.
Olivia-Kiara: Since the relative speed difference of 3mph , that means every 20 minutes Kiara gains 1 mile extra over Olivia so she walks the same as distance plus gains another 1 mile extra and since she is 4mph behind to start off , she will need 80 mins to catch up and overtake Olivia
Q 18*3=27 12*4=12 22*8=32 12*9=? Ecpected ans is 36 But my question is why not 27 Because. 18*3=27(1+8)*3=27 12*4=12(1+2)*4=12 22*8=32(2+2)*8=32 12*9=27(1+2)*9=27 why not currect

Wow, that is the most efficient way of thinking about the answer
Very efficient. My formula
Kiaira 5(time) + 0(starting point) =Olivia 8(time) -4(starting 4 miles behind
Time =4/3hr or 80mins. I like your way better.
how calculated one hour 3mph faster than kiara, she would need more than an hour to catch up
7:37 Variant 1: (1+8) * 3 = 27, (1+2) * 4 = 12, (2+2) * 8 = 32, and (1+2) * 9 = 27 again. Variant 2 is the one you explained and the correct answer actually.
I agree 100%. I arrived at the same answer. There is no possible pattern to arrive at 36
@@AM-db7jp Yes true
WOBL not only spells Bowl but also Blow
19:28 the correct answer is D) think of it like a diagonal line and that moves from bottom left to top right with each new image.
17:05 the question states “12*9=?” But you then go into explaining “13*9” instead of the original “12*9”
always bad at math
Bro, I couldn't find the right answer but it's because you have 12*9 so I kept getting 27 but the real problem is actually 13*9 which is 36
@2:15 - for the first problem the alternative is to calculate it first by percentage, utilities is 40%,
Heating is 15% more = 46%
Remaining is 14%
14% of 1500 = 210
The olivia and kiara question
Their relative velocity, v is 8 - 5 = 3mph since they are moving in the same direction. Therefore the time difference, t = d/v =4/3 hrs

Another way
Speed 1 5kmph = 83.33 m/ min
Speed 2 8kmph = 133.33m/m
Let's say in x min they will merge.
83.33*x + 4000 = 133.33*x
X=80
6:46 Actually has two answers, BOWL AND BLOW.
Hi, for the answer to be 36 that would mean it was 13 ie 1+3 multiply by 9 would then be equal to 36..
Yeah there is a typo on this and it was wrecking my brain for a minute..
@@TyeRantz I am glad that I am not the only one that spent time on that wondering HOW????
Wouldn't Olivia be catching up to Kiara and not vice versa? She started behind her.
that is what I was thinking too
I think triangle question answer is 7 because if we consider rest all numbers pairs those are counting to 10
ex:- 8, 2 (8+2= 10)
4,6 (4+6= 10)
3 , missing (3+X=10-->> X=10-3--> 7)
Hence 7 would be the right answer.
I am confused with the word one.. WOBL could also be blow? So would that be wrong?
Volume of cube is side x side x side. So volume for bigger cube is 27 (3x3x3) and smaller cube is 1 (1x1x1). 27 divided by 1 is 27.
First question alternate answer::
15% of 40% = 6% (1.5*4) so we have 46%+40%=86%. Remainer is 14% *1500 = 210 (150 + 15*4 ). Notice the reccurance of 15*4.

what is the triangle answer and why ?
Why wouldnt blow work?

Solution: Lets assume they take time T to meet/catchup and in doing this they cover a total distance of Y.
Since Kiara had a head start of 4 miles, she covered Y in time T by, 5*T+4=Y
Olivia covers Y by, 8*T=Y, equating both,

Here, in the question it was 12*9, but when the puzzle was solved, it was 13*9, that's why the answer is 36.
Second question alternate method would be ... CostOfShoe = x; CashAtHand => 33 = 20%x = 0.2x; So x = 0.2/30 = 165
For the rent problem. multiply 260*4, the total amount the reaming for have to pay=1040, which is 1/5 of the original rent. take 1040*5 =5200. That is the total rent.
