We can say that Let present age of Vikram and Garima be 'b' years and 'g' years respectively. According to question, (b – 4)/(g – 4) = 3/4 4b – 16 = 3g – 12 4b – 3g = 4 ……………………… (1)' (b + 6)/(g + 6) = 4/5 5b + 30 = 4g + 24 4g – 5b = 6 ……………………… (2) Solving equation (1) and (2), we get b = 34 years So the present age of Vikram = 34 years
