The share of A when Rs 25 are divided between A and B so that A gets Rs. 8 more than B is Rs 16.50.
Let us assume B share be x
As per the condition in the question A share be x + 8
Then,
x + (x + 8) = 25
x + x + 8 = 25
2x + 8 = 25
2x = 25 – 8
2x = 17
x = 17/2
x = 8.5
So, A gets x + 8
= 8.5 + 8
= Rs 16.5
