Ans: 200
Ratio of V & B = 6:5
6x+5x=275
x=25
Means that V got=150 & B got=125
Avg of both=275/2
Total*68.75%=275/2
Then Total=200

Let Vinod marks be 6x and Basu's is 5x. Therefore, the sum of the marks = 6x + 5x = 11x.

But the sum of the marks is given as 275 = 11x. We get x = 25 therefore, vinod marks is 6x = 150 and Basu marks = 5x = 125.

Therefore, the combined average of their marks = (150 + 125) / 2 = 137.5.

If the total mark of the exam is 100 then their combined average of their percentage is 68.75

Therefore, if their combined average of their percentage is 137.5 then the total marks would be (137.5 / 68.75)*100 = 200.
