Answer 1

Answer:

280 marks

Step-by-step explanation:

Sushma scored 50% and get 20 marks more than the passing marks

50% = 20 marks above passing marks

Preeti score 40% and failed by 40 marks.

40% = 40 marks below passing marks

Find 50% of the marks

10% = 20 + 40

10% = 60 marks

1% = 60 ÷ 10 = 6 marks

50% = 6 x 50 = 300 marks

Find the passing marks:

Passing marks = 50% - 20 = 300 - 20 = 280 marks

Answer: The passing marks in 280 marks
