Question

By selling a biycle for $4275, a shopkeeper loses5%.For how much should he sell it to have a profit of 5%

Answer 1

Answer:

Step-by-step explanation:

SP=$4275

Loss=5%

CP=SP(100/100-loss%)

CP=4275(100/100-5)

CP=4275(100/95)

CP=4500

Profit=5%

CP=4500

SP=CP(100+profit%/100)

SP=4500(100+5/100)

SP=4500(105/100)

SP=4725

Answer 2

(S.P. of 18 bicycles) - (C.P. of 18 bicycles) = (C.P. of 3 bicycles)
(C.P. of 18 bicycles) + (C.P. of 3 bicycles) = (S.P. of 18 bicycles)
(C.P. of 21 bicycles) = Rs. 16800
(C.P. of 1 bicycle) = Rs. 16800



Or




Answer- Option D

Explanation-

Let C.P. of an item be Rs. x
Then, S.P. = Rs. (120% of x) = Rs. 6x

5
New S.P. = 2 6x

5 = Rs. 12x

5

Profit = Rs. 12x

5 - x = Rs. 7x

5

Profit % = 7x

5 * 1

x * 100 %
