Question 7 Percentage Exercise 10B

36 % of the maximum marks are required to pass a test. A student gets 123 marks and is declared

fail by 39 marks. Find the maximum marks.

Answer:

Solution:-

Let the x be the maximum marks,

Passing marks for the test = (123 + 39) = 162

Then, 36% of x = 162

= (36/100) × x = 162

= x = (162 × 100) / 36

= x = 450

∴the maximum marks is 450.
