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 byall the dealers in June? (Correct to one decimal place)
The total number of computers sold by dealer A during February to June = 94 + 85 + 108 + 98 + 95 = 480
Total number of computers sold by all the dealers in June = 95 + 108 + 102 + 91 = 396
Required percentage = $$\frac{480 - 396}{396} \times 100 =Â \frac{84}{396} \times 100$$ = 21.2%
