Answer 1

Here's your answer...

Let Sonal's age be x.
Let the parent's age at the time of their marriage be a and b respectively.
Then 23 = a+b/2
a+b = 46

Since Sonal was born 1 year after their marriage, their marriage has lasted x+1 years.
Which means that the current ages of the parents are a+x+1 and b+x+1 respectively.
Now,
35 = (a+x+1+b+x+1+x)/3
105 = (a+b+3x+2)
We found that a+b = 46
105 = 46+2+3x
3x = 105-48 = 57
x = 19

Sonal is presently 19 years old.

Answer 2

Answer:

Step-by-step explanation:

Current avg for S, F, M = 35

35*3=105

When S was born, Avg for F & M = 24

24*2=48

105 - 48= 57

57/3=19

Sonal's age is 19 yrs.
