Q. A dealer buys a car listed at 200000 Rs. at successive discounts of 5% and 10%. If he sells the car for 179550, then his profit is:
Answer:
5%
Notes: Equivalent discount
$ = 10+5-\frac{10\times 5}{100} = 14.5\%$
∴ CP = 85.5% of 200000
$ = \left ( \frac{85.5\times 200000}{100} \right )= 171000\ Rs.$
SP = 179550 Rs.
Gain = (179550 – 171000) = 8550 Rs.
$ \therefore Gain\ \% = \frac{8550}{171000}\times 100 = 5\%$
Hence option [B] is correct answer.
