A shopkeeper marks the marked price 25% more than the cost price that is Rs. 1500. After giving two successive discounts of 12% and x% he losses Rs. 15. Find the value of x.
Explanation:
Let the cost price = 1500 Rs.
Marked price = 1500 × 125% = 1875
After giving two successive discounts of 12% and x% loss = Rs. 15
1875 × (100 – 12)% × (100 – x)% – 1500 = – 15
1875 × .88 × (100 – x)% – 1500 = – 15
1650 × (100 – x)% – 1500 = – 15
[1650 × (100 – x) – 150000] /100 = -15
165000 – 1650x – 150000 = – 1500
15000 + 1500 = 1650x
16500 = 1650x
x = 10%
