the ages of Rahul and Haroon are in the ratio 5:7. Five years there sum of there ages will be 56 years what are their present ages?
Answers
Let the ages of Rahul and Haroon be 5x and 7x respectively
ATQ, After 5yrs
Rahul's Age = 5x + 5 and
Haroon's Age = 7x + 5
Given sum of ages ( after 5 yrs ) = 56 yrs
(5x + 5) + (7x + 5) = 56
5x + 5 + 7x + 5 = 56
5x + 7x + 5 + 5 = 56
12x + 10 = 56
12x = 56 - 10
12x = 46
x = 46/ 12
x = 3.8
Age of Rahul = 5 × 3.8 = 19 yrs
Age of Haroon = 7 × 3.8 = 26.6 yrs
→ The question is incorrect as The value of age is evaluating to decimals.
