4 years ago the average age of suhail
and satakshi was 40 years. The
average age of Suhail, Satakshi and
the child is 30 now, what is the age
of child?​

Answer 1

Answer:

2 years

Step-by-step explanation:

let the current ages of suhail and satakshi be x and y years respectively

now it gives (x-4)+(y-4)/2 = 40 >>x+y=88

now (x+y+z)/3=30 (z=child age)

>>>x+y+z=90

>>>z=2years

Answer 2

Answer:

2 year

Step-by-step explanation:

2×40+4×2=88

the age of A+B=88

THE AGE OF A+B+C= 3×30

=90

( A+B+C)-(A+B)

90-88=2

C=2
