Question

vicki scored 81% marks in exam, if he had secured 30 more marks his percentage of marks would have been 85. what was the total marks of the examination?

Answer 1

Answer:

750 marks

Step-by-step explanation:

As given,

30 marks more than 81% of the total (say x) = 85% of x

Therefore, (85 - 81) = 4% of x = 30 marks.

Hence,

(x / 100) × 4 = 30

(x / 100) = 7.5

x = 750

ANS = 750 marks
