Parvinder sold a watch at loss of 5%
Let the cost price of watch =Rs.y
Loss =5%
Selling price =
100
y(100−loss%)
=
100
y(100−5)
=
100
95y
.......(1)
Given that,
Gain=7%
Selling price=
100
y(100+gain%)
=
100
y(100+7)
=

y.......(2)
According to given question,

95
y=27
100
(107−95)y
=27
12y=27×100
y=

27×100
y=

9×100
y=9×25
y=225
Cost price of watch=Rs.225
Hence, y=Rs.225 is the answer.

Step-by-step explanation:
We have,
Parvinder sold a watch at loss of 5%
Let the cost price of watch =Rs.y
Loss =5%
Selling price =
100
y(100−loss%)
=
100
y(100−5)
=
100
95y
.......(1)
Given that,
Gain=7%
Selling price=
100
y(100+gain%)
=
100
y(100+7)
=
100
107
y.......(2)
According to given question,
100
107
y−
100
95
y=27
100
(107−95)y
=27
12y=27×100
y=
12
27×100
y=
4
9×100
y=9×25
y=225
Cost price of watch=Rs.225
Hence, y=Rs.225 is the answer.
