Question

In an examination ramesh gets 28 percent of total marks and failed by 55, while suresh gets 37 percent of total marks and gets 17 more than the passing marks.find the total marks and those necessary for passing

Answer 1

Answer:

Total marks 800

Step-by-step explanation:

Assume the total marks as X and passing marks as Y

Calculating for Ramesh

28% of X = 0.28X

thus, 0.28X + 55 = Y

(Because if he got additional 55 marks than he would reach the passing marks)

Calculating for Suresh

37% of X = 0.37X

thus, 0.37X - 17 = Y

(Because if he got 17 marks less than what he gets he will just hit the passing marks score)

Equating both the equations

therefore 0.28X + 55 = 0.37X - 17

55 + 17 = (0.37 - 0.28)X

72 = 0.09X

X = 800

Woohoo !!!! Here is your answer
