There are 200 grams of roasted chickpea in a 500 gram mixture of chickpeas and grapes.

Kakao/şeker= 2/5

şeker/un=3/8

 Ortak olan şeker sayılarını eşitleyeceğiz

kakao/şeker=2x3/5x3=6/15

şeker/un=3x5/8x5=15/40

kakao/un=6/40=3/20

Cocoa / sugar = 2/5

sugar / flour = 3/8

 We'll equalize the common sugar numbers

cocoa / sugar = 2x3 / 5x3 = 6/15

sugar / flour = 3x5 / 8x5 = 15/40

cocoa / flour = 6/40 = 3/20

Solution

The money received by Ayse is 2x,,Ahmet is 3x and Melis is 5x respectively. 

Melis got 50$

Therefore 5x=  50 $

                 x= 50/5  =10 $

So Ayse got  =   2x=    10x2= 20 $

     Ahmet got = 3x=    10x3= 30$

The total amount is 30+20+50= 100$
