@@sivaskstudios1342 Actual formula is Qtty of cheaper/Qtty of dearer = (d-m)/(m-c); But in question the ratio 2:3 is representing ratio of milk in A (which is dearer as 3/5=0.6) to milk in B (which is dearer 7/20=.35) So in order to put this in formula I have to take reciprocal of this which will give me ratio of cheaper to dearer
@@12th-Maths thank you for your reply sir, but i didnt get, What my confusion, in other problems , we are taking d-m/m-c= what they are given ratio in question. But we r not taking reciprocal on tat. But in this question only we r taking like this. Y sir? I compared other problems sir. Kindly answer me
@@sivaskstudios1342 " d-m/m-c= what they are given ratio in question" : This is not true The correct formula is: (d-m)/(m-c) = Qtty of cheaper/Qtty of dearer
Sir please upload example solutions of applied maths
Why sir? In 10 th problem, you are taking 3/2 in left side
B'coz it is dearer verses cheaper ratio as per question
@12th-Maths but they are given 2:3 only sir.
