Question

in an examination a student required 40% of the total to pass if Rupa gets 185 marks and fails by 15 marks i find the total marks

Answer 1

hola,
pass mark =185+15=200
let x be the total mark
then  40/100*x=200
40x=20000
x=20000/40=500
therefore the total mark =500
i hope this helps u

Answer 2

185+15=200=40% (according to question)
40%=200
So...1%=200/40
Then 100%=200/40×100 =500
