Answer» C.P = xLoss = 5% S.P = x - (5/100)x= x - (1/20)x= (19/20)x ==========================If the watch was sold for 104 ₹ more , then ; C.P = xProfit = 8%S.P = (19/20)x + 104 S.P = x + (8/100)x (19/20)x + 104 = x + (2/25)x 104 = (27/25)x - (19/20)x 104 = (108x-95x)/100 13x = 10400 x = 800----------------------------------Hence the cost price of the watch is ₹ 800 The selling price= (19/20)x = (19/20) × 800 = 760 Rs.

Answer»

C.P = xLoss = 5%

S.P = x - (5/100)x= x - (1/20)x= (19/20)x

==========================If the watch was sold for 104 ₹ more , then ;

C.P = xProfit = 8%S.P = (19/20)x + 104

S.P = x + (8/100)x

(19/20)x + 104 = x + (2/25)x

104 = (27/25)x - (19/20)x

104 = (108x-95x)/100

13x = 10400

x = 800----------------------------------Hence the cost price of the watch is ₹ 800

The selling price= (19/20)x

= (19/20) × 800

= 760 Rs.
