Let Reetu's age 10 years ago be 'x' years. Then, her mother's age 10 years ago = 5x years (x + 10) + 6 = 3/7 × [(5x + 10) + 6] x + 16 = 3/7 (5x + 16) 7x + 112 = 15x + 48 8x = 64 x = 8 Therefore, Reetu's mother's present age = (5x + 10) = (5 × 8 + 10) years = 50 years Hence, Reetu’s mother’s age at present is 50 years.
