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 %
