10. A shopkeeper bought two items at ₹450 each. He sold one at a loss of 10%. At what price should he sell
the other so as to gain 20% on the whole transaction?
Answers
Step-by-step explanation:
C.P. of shopkeeper=®450
Loss = 10%
S.P. of shopkeeper= C.P.×(100-L%/100)
= 450×(100-10/100)
=450×(90/100)
= 450×9/10
= 45×9
=405
Again,
C.P. of shopkeeper=®450
Gain=20%
S.P. of shopkeeper=C.P. ×(100+P%/100)
= 450×(100+20/100)
= 450×(120/100)
= 450×12/10
=45×12
=540
Total C.P. = (®450+450)=®900
Total S.P.=(®405+540)=®945
Profit= S.P. - C.P.
=® 945-900
=®45
Peofit%= Profit/C.P. ×100
= 45/900×100
= 45/9
= 5%
