Question

A student has to get 40% marks to pass in an examination. Suppose he gets 30 marks and fails by 30 marks, then what are the maximum marks in the examination? 

(a) 100

(b) 120

(c) 150

(d) 300

Answer 1

Correct option is (c) 150

Total passing marks = 30 + 30 = 60

Percentage of passing marks = 40%

Let total marks be x

According to the question

\(x \times \frac{40}{100} = 60\)

\(\therefore x = \frac{60 \times 100}{40} = 150\)
