For Ashok
Sum invested = Rs 18000
N.V of each share = Rs 100
M.V of each share = Rs 100 - 20% of Rs 100 = Rs 80
No. of shares bought = Rs.18000Rs.80=225
Dividend on 1 share = 7.5% of Rs 100 = 27.5
Total dividend received = 225 × Rs.7.50 = Rs. 1687.50
For Sandeep
Sum invested = Rs 18000
N.V of each share = Rs 50
M.V of each share = Rs 50+20% of Rs 50 = Rs 60
No. of share bought =Rs.18000Rs.60=300
Now it is given that Ashok and Sandeep receive equal dividend
Total dividend received by Sandeep = Total dividend received by Ashok.
= 1687.50
Dividend on 300 shares = Rs 1687.50
dividend on each share =Rs.1687.50300=Rs.458
Since N.V of each share = Rs 50
on Rs 50 dividend =Rs.458
Rate of dividend =458×50×100%=11.25%
