in an examination ,a student requires 40% of the total marks to pass.if rupa gets 185 mark and fails by 15 marks,find the total marks.[linear equation]..

Solution:

Let us assume that the total marks be T marks.

Then: 40/100 of T = 185 + 15

40T/100 = 200

40T = 200 x 100

T = 20000/40 = 500.

Ans: 500 Marks.
