Correct Answer - Option 3 : 256
Given:
The price of a chocolate in 2018 was Rs. 320.
The price decrease by 20% in 2019 due to low demand.
The price of another chocolate decrease by 40% from 2018 to 2019.
The ratio of the prices of two chocolates in the year 2019 is 5 : 3.
Formula used:
Profit or Gain = Selling price – Cost Price
Loss = Cost Price – Selling Price
Profit percentage = (Profit /Cost Price) × 100
Loss percentage = (Loss / Cost price) × 100
Calculation:
Let the price of 2nd chocolate in 2018 be x.
(320 × 4/5)/(x × 60%) = 5/3
⇒ 64 × 4 = 5/3 × x × 3/5
⇒ x = 256
∴ Price of second chocolate is Rs. 256
