A candidate who scores 30% fails by 5 marks, while another who scores 40% gets 10 more marks than the minimum pass marks. The minimum marks required to pass are

(a) 40

(b) 50

(c) 55

(d) 65

Best answer

**Answer: (b) 50 **

**Solution:-**

Let the total marks be X

According to the question,

X x 30/100 + 5 = X x 40/100 – 10

3 X/10 + 5 = 4 X/10 – 10

4 X/10 – 3 X/10 = 10 + 5

X/10 = 15

X = 150

Then, minimum marks = 150 x 30/100 + 5

= 45 + 5

= 50

Hence, the correct answer is option (b) 50.
