So, a + 5 = b - 4 Or, b - a = 9 -------- (I) And, a - 6 + b - 6 = 27 Or, a + b = 39 ------- (II) On adding equation I and II, We get, b - a + a + b = 9 + 39 Or, 2b = 48 Or, 'b' = 24 On putting value of 'b' in equation I, We get, 24 - a = 9 Or, 'a' = 15 So, present age of 'R' = 15 + 3 = 18 years Therefore, age of 'R' 4 years hence from now = 18 + 4 = 22 years
