@@schandacademy Sir for question 24. the answer will be 285.. Because Number which are divisible by 5 or 7 are 313 but we need to exclude number divisible by 35 . We only want the numbers divisible by 5 or 7 but not by 35. So, we subtract the 28 numbers divisible by 35: 313 - 28 = 285. Therefore 285 natural numbers less than 1000 are divisible by 5 or 7 but not by 35
Hello sr in this question 11 new trick is available for example sum of (1 to 6) is equal to we have do that with 2nd trick for that first select first digit and last digit here 1+6=7 and multiply with total count of that number here 6 is total number is 6 and 6*7 is 42 and divide that number into 2.... 21 is the answer 1+2+3+4+5+6= 21

hello brother here we consider x as an odd number and there is a prperty we all know that when we add even number to an odd number in that case the resulting no is an odd number for eg 1+2=3,3+6=9 and so on so it is correct
the question is about three consecutive odd numbers... and the smalest odd no. is 1 not zero.. i think u habe to study from a KG student he will teach u what is odd no. , what is even and what is whole no. Kaha say aatay hy ya loog. 🧐
@@imirfankhan2 Bro, he said for "whatever X is". He declared a variable without considering " 1 is the smallest odd number". It's okay if you lack the knowledge of variables. Let's not be disrespectful to each other.

in que no 103 , short cut is - 2004 divide by 4 will get remainder 3 (say golu). and unit digit of given question (13) is 3 (say bholu to three). hence bholu to the power golu is twenty seven i.e. (3 to power 3 is 27 ) so unit digit is 7. therefore seven is answer..
@@schandacademy kothari sir have expertise but unable to interact or tech students just reading and solving like a bookworm not explaining pls provide another mentor dear s chand.
Sir, why did u skip qsn no. 19-23 ? I don't understand qsn no. 19 and 20 even after watching it's explanation... So kindly solve those problems also...
There's a formula for that one 1/6n x (n+1) (2n+1).... Substitute 9 in place of n you'll get 1/6 x 9 x 10 x 19 gives you 90x19 divided by 6 you'll get your answer For question 20 you have to know the Roman numerals, it's a late middle age of writing number, like( ii is 2)( iii is 3) (v is 5) here M is 1000, D is 500, C is 100, L is 50 , then arrange the sequence from big to small like so M>D>C>L

In question 24, shouldn't we subtract 28 twice? One to avoid double counting and one to remove answers divisible by 35. So shouldn't answer be 285?
Yes
Yes
Sir in question no. 11 We can also use the Sum of n natural number formula from arithmetic Progression ?
At 13th question we also use division rule...(1+4)-(0+3)=2...So answer is 2..
in que no 103 ,
short cut is - 2004 divide by 4 will get remainder 3 (say golu).
and unit digit of given question (13) is 3 (say bholu to three).
hence bholu to the power golu is twenty seven i.e. (3 to power 3 is 27 )
so unit digit is 7. therefore seven is answer..

7 race to 95-3 race to 58 what is the unit number of this
Plz solv it sir
Why didn't you explained factorial sir?🙏
sor ji please make a book for aptitude for agriculture students 😀
Sir, why did u skip qsn no. 19-23 ? I don't understand qsn no. 19 and 20 even after watching it's explanation... So kindly solve those problems also...
For 19 no formula is
Greatest 3 digit no completely divisible by 4 minus smallest 3 digit no completely divisible by 4 diveded by 4 plus 1
There's a formula for that one 1/6n x (n+1) (2n+1).... Substitute 9 in place of n you'll get 1/6 x 9 x 10 x 19 gives you 90x19 divided by 6 you'll get your answer
For question 20 you have to know the Roman numerals, it's a late middle age of writing number, like( ii is 2)( iii is 3) (v is 5) here M is 1000, D is 500, C is 100, L is 50 , then arrange the sequence from big to small like so M>D>C>L
