Answer 1

Answer:

Cost Price of

1

rd

3

1

×450=RS.150

Selling Price of

3

1

rd

of goods = 150×

100

90

=Rs.135 [10% loss]

The total selling price with 20% gain should be 450×

100

120

=Rs.540

Therefore, the selling price of the remaining

3

2

rd

of the goods should be 540-135= Rs. 405

The cost price of the remaining

3

2

rd

of the goods is Rs. 300.

Therefore, Gain % =

300

405−300

×100=35%

Thus, the remaining
