Question
The ratio of the ages of Pari and Qureshi is 5:9. If the
ratio of the age of Pari after 3 years and the age of Qureshi after 9 years is 1:2, then find the age of Qureshi 6 years from now?Solution
ATQ, Let we can assume that the age of Pari and Qureshi as = 5x and 9x Then Ratio will become as = (5x + 3)/(9x + 9) = 1/2 10x + 6 = 9x + 9 10x – 9x = 9 – 6 x= 3 by putting the value of x in Qureshi age then the age of Qureshi will be = 9 x 3 = 27 Therefore, the Age of Qureshi after 6 years will be = 27 + 6 = 33 years
