marks in examination.
​

Answer 1

Answer:

Step-by-step explanation:

LET THE TOTAL MARK BE x

RAJINI GOT 15 MARKS LESS THAN THE PASSING MARKS

SO PASSING MARKS = MARKS SCORED BY RAJINI + MARKS BY WHICH HE FAILED

                                    = 150+15

                                    =165

PASSING MARKS = 33% OF TOTAL MARKS

165= (33*x)/100

x= 16500/33

  = 500

SO TOTAL MARKS = 500
