The following table shows of different items in different shops and respective spelling prices per unit.

Find the percentage of total reverse which comes from cooler from shop E, Considering all given items are being sold from shop E and from all the given shops only given three items are being sold (rounded off to three decimal places)
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. 4.226%
Calculation:
Total cooler sold by shop E = 4000 × (1/10)
⇒ 400
Selling price of 400 coolers = 400 × 8000
⇒ 3200000
Total ACs sold by shop E = 4000 × (5/10)
⇒ 2000
Selling price of 2000 ACS = 2000 × 26500
Total Fans sold by shop E = 4000 × (4/10)
⇒ 1600
Selling price of 1600 Fans = 1600 × 12200
⇒ 19520000
Now,
Required % = [3200000/(3200000 + 53000000+ 19520000)] × 100
⇒ [3200000/(75720000)] × 100
⇒ 4.226 ≈ 4.23%
