Question 57

The following bar chart shows the marks obtained (out of 100) by a student in 6 different subjects in an examination.

The total marks obtained by the student in S2 and S4 taken together is what percentage more than the marks obtained by the student in S5? [Give your answer correct to 2 decimal places.)

Solution

The total marks obtained by the student in S2 and S4 taken together = 67+83

= 150

marks obtained by the student in S5 = 85

Percentage more = $$\frac{150-85}{85}\times100$$

= $$\frac{65}{85}\times100$$

= $$\frac{6500}{85}$$

= 76.47%
