Question

Mr. Tandon purchased a computer for computer he lost 5% and on microwave he ga cent. Mr. A sells a bicylce to Mr. B at a profit of 209 25%. If Mr. C pays 1,500, what did Mr.​

Answer 1

Answer:

Given in the question-

CP of computer = Rs.32000, Loss % on computer = 5%.

CP of microwave = Rs. 6500, Gain % on microwave = 15%.

Now, to find the selling price (SP) of a computer, we use the formula SP=100−l%100×CP , since there is a loss.

Putting the value of CP of computer, loss % in the above formula we have-

SP=100−5100×32000=95100×32000=30400

Now, to find the selling price (SP) of a microwave, we use the formula SP=100+P%100×CP , since there is a profit.

Putting the value of CP of computer, profit % in the above formula we have-

SP=100+15100×6500=115100×6500=7475

Now, the total CP is = CP of computer + CP of microwave

=32000+6500=38500

Now, also the total SP = SP of computer + SP of microwave

=30400+7475=37875

Now since the total CP > total SP, so there is a loss

Loss = CP – SP = 38500 – 37875 = Rs. 625

So, the loss % will be lCP×100% , where l is the loss and CP is the Cost Price.

Putting the values of loss and CP we have-

Loss % =62538500×100=12577=1.62%

The loss is 1.62%, so none of the above options are correct.

Note – Whenever such types of questions appear then first write down the things given in the question and then find the selling price of both the items. Then if the selling price < cost price then there will be a loss and to find the loss % use the formula, lCP×100% , which will give the loss%.
