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
Hence, Monthly salary of Shankar is Rs. 28,000.
By investing Rs. 1552, income = Rs. 128.
By investing Rs. 97, income = = Rs. 8.
Dividend = 8%
Cost of Rs. 100 stock = Rs. (100+4) = Rs.104
Cost of Rs. 4500 stock = = Rs. 4680
Cash realised = Rs. (106.25 - 0.25) = Rs. 106.
Investment = Rs. [20 x (50 - 5)] = Rs. 900.
