The income from online sales of a shop is given below. In which month is the sales the highest?

The correct option is C 3rd month

For the amount of online sales made, we need to multiply the values by 1,000.

Observing the graph, we get:
Amount of sales in 1st month = 20,000
Amount of sales in 2nd month = 18,000
Amount of sales in 3rd month = 23,000
Amount of sales in 4th month = 20,000


So, the sales are the highest in the 3rd month.

∴ Option (C) is correct.
