Answer 1

Step-by-step explanation:

The average age of 4 brothers= 12years

That means 12+12+12+12= Total 48 years

Now, their mother will be included and and the average is increased by 5 years.

That means 12+5=17

Now they have total 5 person included mother.

Therfore total age= 17*5= 85 years.

Hence mother age= 85yrs - 48 yrs when you seperate mother age from son's age= 37 years.

Ans:- The age of mother will be 37 years.
