The total number of computers sold by dealer A during February to June is what percentage more than the total number of computers sold by all the dealers in June? (Correct to one decimal place)
Answer & explanation
Correct answer: option 2
Total number of computers sold by dealer A during February to June
= 94 + 85 + 108 + 98 + 95
= 480
Total computers sold by all in june = 95 + 108 + 102 + 91
= 396
Required percentage = \(\frac{480 - 396}{396}\) × 100
= \(\frac{ 84 }{396}\) × 100
= 21.2%
