Answer 1

★ उत्तर - 16 लीटर

Hey dear,

I'd prefer to explain this in english.

◆ Answer-
16 L

◆ Explanation-
# Given-
Diluted milk = 176 L
Percentage of water = 20%
Desired water percentage = 12%

# Solution-
Initially,
Water in milk = 20% × 176
Water in milk = 35.2 L

Let x be amount of water evaporated to get 12% water. Then,
(35.2-x)/(176-x) = 12%
100(35.2-x) = 12(176-x)
3520 - 100x = 2112 - 12x
1408 = 88x
x = 16

16 L water have to be evaporated to get 12% water in milk.

Hope this helps...
