Question

A glass contains whiskey and water in the ratio 2: 13. The volume of the contents is increased by 40% by
adding whiskey to this. From this resultant mixture 63 ml is withdrawn and then 45 mlwater is added. The resultant
ratio of whiskey to water in the final solution is 1: 2. What is the initial amount of whiskey inside the glass?
a) 18 ml
b) 36 ml
c) 54 ml
d) 72 ml
e) 270 ml

Answer 1

Whiskey : water

2 : 13

100 % = 15

140 % = 21

Whiskey : water

8 : 13

8x - 24 1

----------------- = ------

13x -39+45 2

By solving , we get X = 18

Initial amount of whiskey is , 18*2

=> 36 ml ✅

I hope you understand this method,
