Answer 1

Answer:

500:51

Step-by-step explanation:

One Litre he Pays = Rs 6.4

Lets assume he add x litre water in milk

Total he have now = 1+x

He gets income = 8*(1+x) = 8 + 8x

Profit = 8 + 8x - 6.4 = 1.6 + 8 x

Profit = 37.75%

.3775* 6.4 = 1.6 + 8x

.3775*0.8 = 0.2 + x

x = 0.102 Litre

1.102 have 1 litre milk and 0.102 litre water

Ratio is 1 : 0.102

1000:102
