Question

In an exam , A scored 60% more than
the pass mark and his score is 30
marks less than the maximum marks.
If a scored 80% of the maximum marks,what is the pass mark?​

Answer 1

Answer:

30 MARKS

Step-by-step explanation:

let maximum marks be X

passing marks be Y

------------------------------------------------------

Case 1

X - 30 = 80/100 X

X - 30 = 4/5 X

5X - 150 = 4X

X = 150

SO MAXIMUM ARE 150

------------------------------------------------------

A'S SCORE IS (150 - 30) = 120 MARKS

NOW CASE 2

60/100X + Y = 120

3/5X + Y =120

90 + Y = 120

Y = 30

------------------------------------------------------

SO PASSING MARKS ARE 30 MARKS.
