Answer 2

Answer:

(c) 150

Step-by-step explanation:

see because

he wants 40%marks

he get = 30 marks

and failed by = 30 marks

means, he want (30+30) marks to pass and these 60 marks are 40%

let maximum (total) marks be x

then %=no. want / maximum number*100%

now

40% = 60/x*100%

x = 6000/40

= 150

M.M. = 150
