Detailed Solution
Download Solution PDFLet the new price of the pastry be Rs. ‘x’
⇒ The ratio of old to the new price of pastry = 48 ∶ x
Now,
⇒ The ratio of earning of bakery = Ratio of sale of pastries × Ratio of the price of pastries
⇒ 4 ∶ 5 = 5 ∶ 8 × 48 ∶ x
∵ The compound ratio of ratios a ∶ b and c ∶ d is ac ∶ bd
⇒ 4/5 = 30/x
⇒ x = 30 × 5/4 = Rs. 37.50
∴ Price of the pastry is reduced by = 48 - 37.50 = Rs. 10.50Last updated on Jun 2, 2025
