November 22, 2024
Explanation:
(18) Let the original price of chocolates be P.
Final price = Original Price x MF1 x MF2
Here, MF is multiplying factor and it is equals to (1 + % change) in case of increase & equals (1 - % change) in case of decrease.
∴ Final price = Original price x (1 + x%) x (1 - x%)
= 96.76%P=P [1−(x%)2]
= 96.76% P = P – P (x%)^2
= 96.76% P = 100% P – (x%)^2 P
= 96.76 = 100 – x^2%
= x^2% = 3.24
= x^2 = 324
= x = 18 Ans.
