Study the given graph and answer the question that follows.
The total number of computers of type A sold in January and Mayis what percentage less than the total number of computers of type B sold from March to May? (correct to one decimal place)
Answer & explanation
Correct answer: option 4
Number of computers of type A sold in January and March = 250 + 350 = 600
Total number of computers of type B sold from March to May = 350 + 325 + 425
= 1100
Required percentage = \(\frac{1100-600 }{1100}\) × 100
= \(\frac{500 }{1100}\) × 100
= 45.5%
