Answer:
Rs. 140
Step-by-step explanation:
Let x be the CP of the table.
SP of table = 1.1x.
If the cost price were 5% less then the cost price would be = 0.95x
The selling price sold at 7 more is equal to = 1.10x + 7
If it were sold this amount the profit would have been 0.20x
This means:
1.10x + 7 - 0.95x = 0.20x
=> 0.15x + 7 = 0.20x
=> 0.20x - 0.15x = 7
=> 0.05x = 7
=> x = 7/0.05 = 140
The cost price is equal to Rs 140.
