By selling a watch for a certain amount. Deepika suffered a loss of 10%. By selling the same watch for 140 more, she would have gained 4%. What was the cost price of the watch?
Given:
Loss = 10%
By selling the same watch Rs. 140 moreGain is 4%.
Solution:
Let the cost price be Rs. 100
Case1
selling price when loss is 10%
SP = Rs. 100 – 10%
Rs. 100 – 10
= Rs. 90
Case 2
selling price when gain is 4%
Rs. 100 + 4 = Rs. 104
According to question case 2 - case1
Difference = Rs. (104 – 90) = Rs. 14
If the difference is Rs. 14, the cost price = Rs. 100
If the difference is Rs. 140, the cost price = Rs. 100/14 × 140
=> Rs. 1000
