Answer 1

Answer:

9 I hope you understand this

Answer 2

40 Years
Explanation:
Let us assume Kamla's present age is K, and her son's present age is S.
It is given that in present, Kamla is 4 times as old as her son. This means that her age will be 4 times his son's age.
So, K = 4S, Equation 1
It is also given that 5 years ago, her son's age was 1/7 of her age. So, Kamla's age 5 years ago will be K-5, and similarly, her son's age 5 years back will be S-5.
But son's age is 1/7 Kamla's age.
So (K-5)/7 = (S-5), Equation 2
Let us simplify Equation 2.
K - 5 = 7S-35
K+35-5=7S
K+30=7S
Substituting Equation 1.
4S + 30 = 7S
30=7S-4S
30=3S
S=10
We got Son's present age. So, Kamla's present age = K = 4S = 4*10 = 40 Years.


Hope this helps you
