Question

There are 5 friends in a class who get marks in the ratio 3:4:5:6:7. The maximum marks are the same in each case. The total marks obtained by the 5 are ${\frac{3}{5}}^{th}$ the maximum obtainable marks. How many friends got more than $70\%$ of the total marks?

• A. 0
• B. 1
• C. 2
• D. more than 2

Answer 1

The correct option is C 2

Lets assume that the maximum marks are 100. total marks available =500

Total marks obtained by all 5 together $=\frac{3}{5}\times 500=300$

Which is divided in the ratio 3:4:5:6:7

Marks are 36, 48,60, 72 and 84. only 2 students get more than $70\%.$
