Question
Present age of Anil is 20% less than that of Bijender
and 5 years hence from now, the ratio of Bijender and Shinu’s age will be 2 : 3 respectively. If the sum of the present ages of Anil, Bijender and Shinu is 85 years then find the present age of Bijender.Solution
ATQ, we can say that The age of Bijender and Shinu after 5 years = 2x and 3x yrs So, Present ages of Bijender and Shinu = (2x – 5) and (3x – 5) yrs And Present age of Anil is = 4/5(2x – 5) 4/5(2x – 5) + (2x – 5) + (3x – 5) = 85 x = 15 Hence, the present age of Bijender is = (2x - 5) = ((2 x 15) - 5) Bijender = 25 yrs age
