A man invested 20,000 in some shares in the ratio 2 : 3 : 5, which pay dividends of 10%, 30% and 20% respectively on the investments in that year. Find the total dividend income of the man.

The total dividend income is 4200.

Split 20000 in ratio 2:3:5 as 4000, 6000, 10000.

Dividend on first = 10% of 4000 = 400.

Dividend on second = 30% of 6000 = 1800.

Dividend on third = 20% of 10000 = 2000.

Total = 400 + 1800 + 2000 = 4200.
