The given table represents the number of computers sold by four dealers A, B, C and D during the first six months of 2016. Study the table carefully and answer the question that follows.

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)

21.2

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%
