Aptitude - Ratio and Proportion - Discussion

Ratio and proportion is our topic in math it is fun and easy I love to learn ratio.

A B C
3:4
5:6

First multiply AxB as 3x5=15, likewise multiply 4x5=20 and finally multiply 4x6=24.

That is 15:20:24.

@Ramesh concept is ok but will it work for all the sums?

x is total money. Now, shares of A, B, C and D comes out to be 5x/14, 2x/14, 4x/14, and 3x/14. (5+2+4+3=14), Now Acc. to question, C is getting 1000 more than D.

Which means "[(4x/14)-(3x/14)]=1000" find x from here, which comes to be 14000. Now we can find B's share as (B=2x/14), put value of x, and B comes 2000.

In the same way we can find share of any one.

Very simple logic. Here question clearly saying that C gets 1000 more than D that is 4x-3x=1000 and x=1000.

Then for A, 5x = 5*1000 = 5000.
B, 2x = 2*1000 = 2000.
C, 4x = 4*1000 = 4000.
D, 3x = 3*1000 = 3000.

It is very simple Here A:B:C:D::5:2:4:3.

And diff. Between c & d =1000

So share of B = B/C-D*1000 = 2/4-3*1000 = 2000
