Q no. 21, exercise 3, ML Publication, share and dividends

Given In first case;

Total investment = Rs. 10400

Rate of dividend = 6%

Market value of each share = Rs. 104

Total dividend = (10400 x 6)/ 104 = Rs 600

In second case, investment = Rs 11440

Rate of dividend = 10.4% Market value of each share = Rs 143

Therefore, total dividend = (11440 x 10.4)/ 143 = Rs 832

Total dividend from both cases = Rs. 600 + Rs. 832 = Rs. 1432
