Question

Rs 6500 were divided equally among a certain number of person had there been 15 more persons each would have got rupees 30 less. find the original number of person.

Answer 1

Let number of persons be n.

Share of each person = 6500/n              ------------ (i)

There been 15 persons = 6500/n+15     ---------- (ii)

Solving (i) and(ii) we get

= 6500/n - 6500/n+15 = 30

= 6500*15/n^2 + 15n = 30

= 6500*15/30 = n * n +15n

= 3250=n * n +15n

= n^2 + 15n-3250 = 0

= (n+65)(n-50) = 0

n=-65, n=50

Since n cannot be negative. n = 50
