प्रश्न
The price of a chair is reduced by 25%. What is the ratio of:
(i) Change in price to the old price.
(ii) Old price to the new price.
उत्तर
Let old (original) price of a chair = Rs. 100
Reduction = 25% = Rs. 25
∴Reduced price = Rs. 100 – Rs. 25 = Rs. 75
(i) Ratio between change in price and old price = 25 : 100 = 1:4 (Dividing by 25)
(ii) Ratio between old price and new price = 100 : 75 = 4:3 (Dividing by 25)
