Let cp of the article = x at 5% gain sp of article = x + (5/100)x = 1.05x at 5% loss sp of article = x - (5/100)x = 0.95x given that 1.05x - 0.95x = 1650 ⇔0.1x = 1650 ⇔ x = 1650/0.1 ⇔x = Rs. 16500

Let cp of watch=Rs x profit=5% sp=(100+p/100)×cp =(100+5/100)×x =105x/100 when loss of 5% sp=(100-5/100)×x =95x/100 105x/100-1650=95x/100 105x/100-95x/100=1650 10x/100=1650 10x=165000 x=16500 CP=Rs 16500

at 5% gain sp of article = x + (5/100)x = 1.05x
at 5% loss sp of article = x - (5/100)x = 0.95x
given that 1.05x - 0.95x = 1650
⇔0.1x = 1650
⇔ x = 1650/0.1
⇔x = Rs. 16500
profit=5%
sp=(100+p/100)×cp
=(100+5/100)×x
=105x/100
when loss of 5%
sp=(100-5/100)×x
=95x/100
105x/100-1650=95x/100
105x/100-95x/100=1650
10x/100=1650
10x=165000
x=16500
CP=Rs 16500
