RRB Assistant Loco Pilot and Technician Model Paper 3 with solutions

(b) Let uncle’s present age = x
Rahim's present age = y
x – y = 30 ...(i)
After 7 year
(x + 7) + (y + 7) = 66
x + y + 14 = 66
x + y = 52 ...(ii)
combining (i) and (ii) we get
(x + y = 52) + (x – y = 30)
2x = 82
x = 41
Uncle's age is 41 years
