A) Rs. 600
B) Rs. 650
C) Rs. 700
D) Rs. 750
Correct Answer: A
$ \therefore $ Selling price $ =\frac{(100-Discountpercent)\times Markedprice}{100} $ $ =\frac{90\times 840}{100}=Rs\text{.}756 $ Now, dealer still gains a profit of 26%.
$ \therefore $ CP of cycle $ =\frac{100\times SP}{100+Profitpercent} $ $ =\frac{100\times 756}{(100+26)}=\frac{75600}{126}=Rs.600 $
