ATQ, 10 years ago, let the age of âBikashâ = âxâ years 10 years ago, age of âArmaanâ = 2x years 2 years ago, age of âArmaanâ = (2x + 8) years 2 years ago, age of âBikashâ = (x + 8) years 2 years ago, age of âChetnaâ = (2x + 8) + (x + 8) = (3x + 16) years 5 years in the future, age of âArmaanâ = (2x + 15) years 5 year in the future, age of Chetna = (3x + 23) years Given that 2x + 15 + 3x + 23 = 5x + 38 = 58 Or, 5x = 20 Or, x = 4 Hence, current age of Bikash = x + 10 = 14 years
