Question
In four years, the total age of 'Ravi' and 'Manoj' will be
60 years. Twelve years ago, Ravi was 10 years younger than Manoj. What will be Manoj's age 3 years from now?Solution
ATQ,
Let present ages be:
Ravi = p
Manoj = q
(p + 4) + (q + 4) = 60
β p + q = 52 βββ (i)
p - 12 = q - 12 - 10
β p = q - 10 βββ (ii)
(q - 10) + q = 52
2q = 62
q = 31
Manoj's age in 3 years = 31 + 3 = 34 years
