Question

A student get 30% of the maximum marks but fails by 30% and another student gets 45% and gets 15 more marks by minimum. Find maximum marks and % necessary for passing

Answer 1

Answer:

Total marks for the examination = 300

The required percentage of marks for passing = 40 %

Step-by-step explanation:

Difference between their percentage is 45 - 30 = 15

Difference between their marks is 30 +15 = 45

Total marks for the examination

= 100 × 45 ÷ 15

= 300

45% of marks = 45×300÷100

= 135

which 15 more than the required minimum marks for passing

the required minimum marks for passing = 135 -15 = 120

The required percentage of marks for passing

= 120 ×100÷300

= 40

Total marks for the examination = 300

The required percentage of marks for passing = 40 %
