Correct Answer:
B) 1 :10
Description for Correct answer:
Let the quantity of milk purchase be x and quantity of water added be y.
Then, ratio of water to milk be y : x.
CP = 6.4x
SP = 8(x+y)8(x+y)
Profit per cent = 37.5%
Therefore, 8(x+y)=6.4×1.3758(x+y)=6.4×1.375
8x + 8y = 8.8x
=> 8y = 0.8x
=> xy=808=101xy=808=101
=> y : x = 1: 10
