Question
At the moment, Anuj and Bishnu have ages in the ratio of
3:4, respectively. If Bishnu's current age were 20% higher, the age gap between Anuj and Bishnu would be 18 years. What is Anuj's current age?Solution
ATQ, Let the present age of Anuj and Bishnu be 3x and 4x years, respectively. then, we can say that 1.2 Γ 4x β 3x = 18 Or, 4.8x β 3x = 18 Or, 1.8x = 18 Or, x = 1.8/18 = 10 Therefore, present age of Anuj is = 3x = 30 years
