Answer 2

Hey there!

Answer:

(c) 72

Step-by-step explanation:

Let age of Waheeda be 12Y years.

Now, according to question,

Granddaughter age (in Months) = 12Y

Granddaughter age( in Years) = 12Y / 12  = Y

Grand daughter age (in Weeks) = 52Y       [∵ 1 year = 52 weeks]

Granddaughter age (in Days) = 52Y * 7

Now,

Son's age (in weeks) = 52Y * 7

Son's age (in Years) = 52Y*7/52 = 7Y

And given,

Sum of ages = 120

12Y + 7Y + Y = 120

20Y = 120

Y = 6

So, Age of Waheeda = 12Y = 12 * 6 = 72 years

Hope It Helps You!
