• # question_answer The total cost of 30 purses and 20 wallets is Rs. 8500. What will be the total cost at 117 purses and 78 wallets? A)  Rs. 32,150                    B)  Rs. 33,510 C)  Rs. 33,550                    D)  Rs. 33,150

Correct Answer: D

Solution :

If the C.P. of 1 purse by Rs. $x$ and that of 1 wallet be Rs. $y$, then $30x+20y=8500$ Dividing both sides by 10, we have $\Rightarrow$ $3x+2y=850$ Multiplying both sides by 39. $117x+78y=850\,\,\,\,\,39$ =Rs. $33150$
