Michel earns Rs. 135 by investing Rs. 1620
To earn Rs. 8 how much he have to invest...?

Number of shares = = 540.
Face value = Rs. (540 x 10) = Rs. 5400.
Annual income = = Rs. 648.
Cost of 1 share =
Cost of 96 shares = = Rs. 912.
Cash realised= Rs. (106.25 - 0.25)

Let the monthly salary of Shankar be = Rs.x
Amount invested on expenditure = 25% = x/4;
Remaning amount = 3x/4;
Amount invested on children education = 20% i.e = 3x/20;
Remaining amount = 3x/4 - 3x/20 = 3x/5;
Remaining amount invested in three different schemes i.e is 1/3(3x/5)
=> x/5 = 5600
Therefore x = 28000
