Hi Kartik.
The solution to the problem goes like this -
Since the selling price is 5.4 and the profit percent is 33.3, you can find out the cost price to be 4.05.
Now think that milk costing 4.50 was pure milk, what will be the quality of milk having cost 4.05.
It'll come out to be 90% (4.05/4.50).
So the answer is 90% or 9/10.
Thanks a lot , I got it now
great videos .
Sir i got the ratio 9:1 not 9:10.
I did,
Take milk(pure) = x litres.
Total price = 4.5x
Take water = y litres.
Milk sold at 5.4 / ltr (given)
So,
Total selling price = 5.4(x+y)
Since profit = 100/3%
[{5.4(x+y) - 4.5x}/4.5x]*100 = 100/3
Solve this to get the ratio.
I got x:y = 9:1
Is there a mistake? Can't find one
Great Work but could u please explain the logic behind 16+x in the 40 litre question. Thanks !
thanks a lot for all the videos... they are superb... bt the qts which you pose at the end are lil difficult
Sir, why you stopped teaching in Hindi ? I found when you explain in Hindi I am able to understand concepts in depth, but in English I really get sleepy. I think Hindi is your strength and you can express your ideas better in Hindi compared to English and we come to you to understand things which we didnot understand any where else. Thus, Please make videos in Hindi only. English is another level of struggle in understanding concepts of maths.
SP - CP = 5.4 - 4.5 = 0.9 = 0.9* 100 = 90% Is this right?
can we do this by alligation
i m getting confused regarding the quality. am not getting the logic behind finding the quality from cost. sir plz can u explain.
cold u please give the solution, i worked it out to be 13/37 , dosent seem correct to me
.....
3:2
Honestly last vala nhi bana :(
Look !!!! Carefully !!!!
He sells it at a profit of (100/3)% now % means per 100 so now remove % and write it as (100/300) it gives (1/3) .
that gives ratio between profit & CP ( profit / cost price ) it means that if ur COST PRICE is 3 THEN PROFIT is 1 & SP is 4 .
But cost price is 4.5 . So multiply it with 1.5 to get the cost price 4.5 so now 3*1.5=4.5 then profit is 1.5 & SP is 4*1.5=6.
SO SP of PURE milk HAS TO BE 6 Rs TO GET A profit of (100/3)% but he gets this profit by SP of 5.4 Rs .
SO 6 Rs is cost of 1L milk .
1Rs is cost of 1L/6 milk
5.4 Rs is cost of (1L/6)*5.4=0.9L REST 0.1 L is water . Now get the ratio M:W=9:1
Abhijeet kumar Got it bro !!
Thanks for ur time :D :*
