Heyaa ❤️
Here's the solution ☺️
_________________
Let the amt. of alcohol be x.
Amt of alcohol in the 400 ml solution = 15/100×400=60 ml
Add x ml alcohol to the solution.
(60ml+x)/(400ml+x) × 100 = 32
(60ml+x)/(400ml+x) = 32/100 = 8
1500ml + 25x = 3200ml + 8x
17x = 1700ml
x = 100ml
100ml of alcohol must be added.
