let the max mark be x n passing mark be y.
peter got 30% of max mark =.3x i.e (x*30/100)
but he failed by 10 mark
therefore passing mark i.e y=.3x+10
now, paul got 40% of max mark=.4x
but he get 15 marks more than passing mark
therefore passing mark i.e y= .4x-15
now from eq (i) n eq(ii)
.4x-15=.3x+10
x=250 i.e max mark
therefore passsing mark(put value of x)
y=.4x-15=.3x+10= 85
ans:D
