Let x be the number
15%x - 40 = 75%x + 80
15/100x - 40 = 75/100x + 80
15/100(x) X 100 - 40 x 100 = 75/100(x) X 100 + 80 x 100
15x - 4000 = 75x + 8000
75x - 15x = 8000+4000 ( transpose)
60x = 12000
60x/60 = 12000/60
X= 200
Maximum marks = 75% x 200 + 80
= 150 + 80 = 230
Hope this helps you.... if yes then pls mark as branlist

It wrong the answer should be: Max marks:- 200 ; Percentage of passing marks:- 35%
But 200 is correct as given
