Solution : Let the marks scored by Sonia be X.

Rohit scored 45 more marks than Sonia. So, marks scored by Rohit = X+45

Raman scored 25 marks less than Rohit.So, marks scored by Raman = X+45-25 = X+20

Rohan scored 75 marks which is 10 more than Sonia.

So, marks scored by Rohan = Sonia marks – 10 = 75

=> X – 10 = 75

=> X = 75+10 = 85

Rohit marks = X+45 = 85+45 = 130

Raman marks = X+20 = 85+20 = 105

Ravi get 34 marks more than Raman . Ravi score = 105+34 = 139

Ravi’s score is 50 less than, maximum marks of the test.

Hence, Maximum marks = 139 + 50 = 189

Percentage of marks scored by Ravi = $\frac{139*100}{189}$ = 73.5% which is close to 70% out of the options given.

Hence, OPTION(b)
