Let’s suppose three numbers are 3x, 4x, 5x. According to question:

3x + 5x = 76 + 4x

=> 4x = 76

=> x = 19

The largest number is 5x => 5*19 = 95 - (a)

Total quantity of mixture = 60L

Milk and water are in ratio of 2:3. Thus,

Milk = 24L, Water = 36L

Let ‘x’ is added to mixture, so that new ratio is 1:2,

New quantity of milk = 24, water = 36+x

=> 24/36+x = ½

=> x = 12 - (c)
