Present age of Raj and Arun is in ratio 9 : 10. The ratio of their ages 8 years from now will be 11 : 12. What will be sum of their ages ( in years ) 3 years from now?
Answer & explanation
Correct answer: option 2
Raj : Arun
9 : 10
↓ +2R → 8years
11 : 12
+2R → 8 years
+1R → 4 years
Therefore,
Raj Present age = 9 × 4 = 36 years
Arun Present age = 10 × 4 = 40 years
After 3 years, Raj age is =36 +3 = 39
Arun age is =40 + 3 = 43
Sum of their ages is = 39+43 = 82
