Question
Anil’s present age is 3/8 of his father’s present
age. Anil’s sister is 4 years older than him. The ratio between the present age of Anil’s father’s and Anil’s sister is 12:5. What is Anil’s present age?ÂSolution
Let the Anil’s father’s age be x Anil’s present age = 3/8 x Anil’s sister’s present age = 3/8 x + 4  According to question, x/(3x/8  + 4) = 12/5 5 x - 36x/8 = 48 4x/8 = 48 x = 96 Anil’s present age = 3/8 x = 3/8 ×96 = 36 years
