Cost of shares = 44(25 + 5 + 1/4) = Rs. 1331
∴ Investment made = Rs. 1331
Now, face value of 1 share = Rs. 25
∴ Face value of 44 shares = Rs. (44 x 25) = Rs. 1100
Now, dividend on Rs. 100 = Rs. 11/2
∴ Dividend on Rs. 1100 = Rs. [(11/2) / 100] x 1100 = Rs. 60.50
Also, income on investment of Rs. 1331 = Rs. 60.50
∴ Income on investment of Rs. 100 = Rs. (60.50 / 1331) x 100 = 4.55%
