The following bar chart shows the number of pens (in '000s) sold by 6 different shops during a given year.
If the cost of each pen is ₹4.50, then what is the average revenue earned per shop?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. ₹90,000.
Explanation :
Total number of pens sold by shops = (15,000 + 18,000 + 22,000 + 27,000 + 21,000 + 17,000) = 120,000
Now, the cost of all pens = 120,000 × 4.50 = 540,000
Now the average cost for all the shops = 540,000/6 = 90,000.
Hence the required average is ₹90,000.
