Solution(By ExamCraze Team)

According to the question,
$$ = frac{{{text{Ram + 2C}}}}{3}$$
= 17 years
Ram + 2C = 51 years.....(i)
$$ = frac{{{text{Wife + 2C}}}}{3}$$
= 16 years
Wife + 2C = 48 years.....(ii)
If Ram age = 33 years old
Put this value in equation (i)
∴ 2C = 51 - 33
2C = 18 years old.....(iii)
Put this value in equation (ii)
Wife + 18 = 48
Wife = 48 - 18 = 30
wife = 30 years old
