Answer 1

Answer:

Give that :-

S.P. = 4185

profit % = 12.5%

C.P. = ?

C.P. = s.p × 100

100+gain%

= 4185 × 100

100 + 12.5

= 418500

112.5

= 3720

Hence C.P. of watch = 3720.

Answer 2

Answer:

Selling price of watch = 418.5

profit% = 12.5

we known that

CP= 100×sp/100+r

wher r= profit

CP= 100×418.5/100+12.5

41850/112.5

= 372

CP= 372
