A) 15%
B) 10%
C) 25%
D) 35%
Correct Answer: D
Solution :
Sol. [d] Total CP of two bicycle = ` \[2\times 3500\] = ` 7000 SP of first Bicycle \[=\,CP\,\times \,\frac{100+\Pr ofit%}{100}\] \[=\,\frac{105}{100}\,\times \,3500\,=\]`3675 Let the SP of second bicycle be ` x Total SP = ` (3675 + x) Gain % = 20% Now, we know that \[SP\,=\,\frac{(100\,+\,gain%)\,CP}{100}\] \[3675\,+\,x\,=\,\frac{(100=20)\times 7000}{100}\] 3675 = x = 8400 x = ` (8400 - 3675) x = ` 4725 \[\therefore \]The other Bicycle must be sold with a gain of \[=\left( \frac{4725-3500}{3500} \right)\times \,100\] \[=\,\frac{1225}{3500}\,\times \,100\,=\,35\]%You need to login to perform this action.
