(Q87) In a mixture 60 litres, the ratio of alcohol and water 2. 1 If this ratio is to be 1 2, then the
quantity of water to be further added is
a. 20 liters
b. 30 liters
b. 40 liters
d. 60 liters
​

Answer 1

60 implies that initially 40 litres was alcohol and 20 litres was water.

the ratio is to be made 1:2 so, alcohol will be 40 litres and water should be twice of alcohol(according to question).

so, finally water should be 40×2 = 80

amount of water added is 80-20=60
