Answer:
Item x will be costlier in 2020.
Step-by-step explanation:
Given:
Amount Increase in price of item x = Rs. 10 per year
Amount Decrease in price of item y = Rs. 15 per year
Price of item x in 2018 = Rs. 50
Price of item y in 2018 = Rs. 90
To find: item which is costlier in 2020.
There is 2 year gap in 2020 and 2018.
So,
Price of item x in 2020 = 50 + 2 × 10 = 50 + 20 = Rs. 70
Price of item y in 2020 = 90 - 2 × 15 = 90 - 30 = Rs. 60
Therefore, Item x will be costlier in 2020.
