A man invests ₹10400 in 6% shares at ₹104 and ₹11440 in 10.4% shares at ₹143. How much income would he get in all? (Assume face value of ₹100)

First Investment:

Total Investment = ₹10400

Market Value per share = ₹104

∴ No. of shares

$= \dfrac{\text{Total Investment}}{\text{MV per share}} \\[0.7em] = \dfrac{10400}{104} \\[0.5em] = \bold{100}$

Rate of Dividend = 6%

As Nominal value is not given, let's assume it to be ₹100 per share

Annual Dividend = No. of shares x Rate of Dividend x Nominal Value per share

$= 100 \times \dfrac{6}{100} \times 100 \\[0.5em] = \bold{₹600}$

Second Investment:

Total Investment = ₹11440

Market Value per share = ₹143

∴ No. of shares

$= \dfrac{\text{Total Investment}}{\text{MV per share}} \\[0.7em] = \dfrac{11440}{143} \\[0.5em] = \bold{80}$

Rate of Dividend = 10.4%

As Nominal value is not given, let's assume it to be ₹100 per share

Annual Dividend = No. of shares x Rate of Dividend x Nominal Value per share

$= 80 \times \dfrac{10.4}{100} \times 100 \\[0.5em] = \bold{₹832}$

Total Income = Income from first investment + Income from second investment
= ₹600 + ₹832
= ₹1432

∴ Total Income = ₹1432
