Answer:
Bharat 17
Akash 29
Average = 23
Step-by-step explanation:
After 3 years bharat will be as old as aakash was when bharat was 8 years old and the ratio of ages of aakash and bharat after 4 years will be 11 is to 7 average age of their present ages
Let say Present age of Bharat = B Years
Present age of Aakash = A Years
After 3 Year Bharat Age = B + 3
Bharat was 8 Years old B - 8 Years before
B- 8 years before Akash age was = A - (B-8) = A-B + 8
=> B + 3 = A -B + 8
=> 2B -5 = A
After 4 years Bharat Age = B + 4
Akash age after 4 years = A + 4
(A + 4) /(B+4) = 11/7
=> 7A + 28 = 11B + 44
=> 7A = 11B + 16
7(2B - 5) = 11B + 16
=> 14B - 35 = 11B + 16
=> 3B = 51
B = 17
A = 2(17) - 5 = 29
Average age = (17 + 29)/2 = 23
