Question

The price of an item x increases by ₹ 10 every year and an item y decreases by

₹ 15 every year. If in 2018, the price of x is ₹ 50 and y is ₹ 90, then which item will

be costlier in the year 2020.​

Answer 1

Answer:

item x will be costlier.

Answer 2

Answer:

2020-2018=2

for the first item x

10×2=20

so the cost of item is

50+20=70

then the second item y

2×(-15)=-30

so the cost of item is

90+(-30)=60
