Question
"Amit and Bishnu's current ages are in the ratio 4:5.
Chintu's age is 40% more than Amit's age. If Bishnu and Chintu's ages sum up to 106 years, what is Amit's current age?"Solution
ATQ, Let, the present ages of 'Amit' and 'Bishnu' be '20a' years and '25a' years, respectively. So, present age of 'Chintu' = 1.4 × 20a = '28a' years ATQ, 28a + 25a = 106 So, a = (106/53) = 2 So, the present age of 'Amit' = 20a = 20 × 2 = 40 years
