Solution
The correct option is D Rs 660 Think about this problem through alligation. Since, A spends 12% of his money and B spends 20% of his money and together they spend 15% of their money-we can conclude that the ratio of the money A had to the money B had would be 5 : 3. Hence, Total money with A = 5×12008=750. Money spent by A = 12% of 750 = 90. Money left with A = 750−90=660.
