Question
The price of a car is lowered by 20% to Rs. 40,000. What was the original price? Also, find a reduction in price.
Solution
Let original price of the car = Rs. 100
Reduction = 20%’ = Rs. 20
∴ Reduced price = Rs. 100 – 20 = Rs. 80
If reduced price is Rs. 80, then original price = Rs. 100
and if reduced price is Rs. 40,000 then original price =`(100 xx 40000)/80`
= Rs. 50000
and reduction = Rs. 50000 - Rs. 40000
= Rs, 10000
