| May | 98 | 102 | 100 | 89 |
| June | 95 | 108 | 102 | 91 |
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)
Show answer & explanation
Correct answer: A
Explanation
The correct answer is Option 1 i.e 21.2.
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 = [(480 - 396) × 100]/396 = (84/396) × 100
= 21.2%
