A shopkeeper sells 2 wrist watches at ₹600 each. On one watch he gains 20% profit and on another watch, he loses 20%. Calculate cost price of both watches.
Answers
Answer:
Given : S.P. of the first wrist watch = 594, Gain% =10%
∴ C.P. of the first wrist watch =
100+profit%
100
×S.P.
=
(100+10)
100
×594
=
110
100
×594= 540.
Similarly, C.P. of the second watch on which he loses 10% is
=
(100−Loss)
100
× S.P.
=
(100−10)
100
×594=
90
100
×594= 660.
To say whether there was an overall Profit or Loss, we need to find the combined C.P. and S.P.
Total C.P. of the two watches =540+660= 1,200.
Total S.P. of the two watches =594+594= 1,188.
Net Loss =1,200−1,188= 12.
Loss% =
C.P.
Loss
×100
=
1200
12
×100=1%.
Answer:
Given : S.P. of the first wrist watch = 594, Gain% =10%
∴ C.P. of the first wrist watch = 100+profit%/100×S.P
= 100/(100+10)×594
= 100/110×594
= 540
Similarly, C.P. of the second watch on which he loses 10% is
100/(100-loss)×S.P.
100/(100-10)×594 = 100/90×594 = 660
To say whether there was an overall Profit or Loss, we need to find the combined C.P. and S.P.
Total C.P. of the two watches = 540+660= 1,200.
Total S.P. of the two watches =594+594= 1,188.
Net Loss =1,200−1,188= 12.
Loss% = C.P./Loss×100
= 12/1200×100
= 1%
