Question

6. On selling a bat for $ 371, a man gains 6%. For how much should he sell it to gain 8%?

Answer 1

Answer:

SP of the bat = $ 371, gain % = 6%.  

Therefore, CP of the bat = {100/(100 + gain %) × SP}

                                      = $ {100/(100 + 6) × 371}  

                                      = $ {(100/106) × 371}  

                                      = $ 350

Now, CP = $ 350 and the desired gain% = 8%.

Therefore, SP = [{(100 + gain %)/100} × CP]  

                      = $ [{(100 + 8)/100} × 350]  

                      = $ {(108/100) × 350}  

                      = $ 378

Hence, the selling price to obtain the desired gain is $ 378.

Answer 2

Step-by-step explanation:

SP= 371

CP= 100/100+gain% * sp

100/106 * 371

CP = 350

desired gain = 8%

SP = 100+gain%/100 * cp

108/100 * 350

SP should be 378
