The line chart given below shows the pocket money of six boys B1, B2, B3, B4, B5 and B6 in a month.
Which of the following statement(s) is/are correct?
I. Pocket money of B2 is 5.25 percent less than the pocket money of B5.
II. Pocket money of B4 is 6.25 percent less than the pocket money of B5.
III. Average pocket money of all the six boys is Rs. 2262.5

Figure for question 59

  • AOnly I
  • BII and III
  • COnly III
  • DOnly II
Correct answer: D

Explanation

I: B2 = 2075 and B5 = 2400, so B2 is 13.54% less, not 5.25%, so I is wrong. II: (2400 – 2250) ÷ 2400 = 6.25% for B4, so II is correct. III: the average = 12975 ÷ 6 = 2162.5, not 2262.5, so III is wrong. Only II is correct.
