Question

The ratio of marks obtained by Vinod and Basu is 6:5. If the average of their percentage is 68.75% and sum of their marks is 275, find the total marks for which exam was conducted.​

Answer 1

Answer:

Step-by-step explanation:

Let Vinod marks be 6x and Basu is 5x.

Therefore, the sum of the marks = 6x+5x=11x

But the sum of the marks is given as 275=11x.

⇒ 11x = 275

⇒ x = 25

We get x=25

therefore, Vinod's marks is 6x=150and Basu's marks=5x=125.

Average of their percentage is 68.75

∴ Sum = 68.75 × 2 = 137.50

Total mark = $\frac{137.5 * 100}{68.75} = 200$

Hence the total mark is 200
