Answer 1

Answer:

600?

Explanation:

Let, the max. marks be, x

The difference between the percentage is 15 percent. So,

15% of x= 90

x = 90/15*100

= 6*100

= 600

Answer 2

Given,

Ajit got 63% and Amit got 78% respectively.

The difference between their marks is 90.

To Find,

The maximum marks

Solution,

Let the total marks be x

Marks scored by Ajit = 63/100*x = 0.63x

Marks scored by Amit = 78/100*x = 0.78x

Now,

0.78x-0.63x = 90

0.15x = 90

x = 600

Hence, the maximum mark in the examination is 600.
