Correct Answer - Option 3 : 100
Given:
Cost price of table and chair = Rs. 500
Total profit = Rs.60
Formula Used:
Profit% = Profit/CP × 100
Loss% = Profit/CP × 100
Calculation:
Total selling price = Rs. (500 + 60) = Rs. 560
Let the CP of table and chair are ‘x’ and ‘y’ respectively.
According to question
CP of table + CP of chair = total CP
⇒ x + y = 500 ----eq.1
SP of table + SP chair = total SP
⇒ 110% of x + 115% of y = 560
⇒ 110x + 115y = 56000 ----eq.2
From eq.1 and eq.2 we get,
X = 300 and y = 200
CP of table = Rs. 300 and CP of chair = Rs. 200
Difference between CP of table and chair = Rs. (300 – 200) = Rs.100
∴ Difference between CP of table and chair is Rs. 100
