▪The ratio between the present age of Ram, Rohan and raj is 4:3:5.
▪The average of their present age is 36
▪The sum of the ages of Ram, Rohan together after 7 years.
Here, Constant is 'n'.
✮ So, according to the 1ˢᵗ condition,
We know that,
✮ So, according to the 2ⁿᵈ condition,
➽ Ram's age = 4 × 9 = 36
➽ Rohan's age = 3 × 9 = 27
➽ Raj's age = 5 × 9 = 45
✦ After 7 years Ram's age will be = 36 + 7 = 43
✦ After 7 years Rohan's age will be = 27 + 7 = 34
∴ After 7 years the sum Ram's and Rohan's age is = (43 + 34) = 77
