Let the present age of Aarav = x years Age of Aarav 5 years ago = (x - 5) years Age of Aarav after 5 years = (x + 5) years Aarav's mothers age 5 years ago = 3(x -5) years Aarav's mothers present age = 3(x -5) + 5 = (3x - 10)years Aarav's mothers age after 5 years = 3x - 10 + 5 = (3x - 5)years According to the question; 3x - 5 = 2 (x + 5) ⇒x = 15 years Hence, option 2 is the correct answer. |
