Let my age 18 years ago be x years My grandmother’s age at that time = 9 x years My present age = (x + 18) years My grandmother’s present age = (9 x + 18) years According to question 3(x + 18 + 9) = (9 x + 18 + 9) 3 x + 81 = 9 x + 27 9 x - 3 x = 81 – 27 6 x = 54 x = 9 Now, ratio of ages 9 years ago = (x + 18 -9 )/(9x +18 - 9) = (9 + 18 - 9)/(9 × 9 + 18-9 )=18/90 = 1:5
