Answers

Hey mate!!!!!

First question

Find max marks.

Maximum mark = no. of questions × marks gain on per Question

=> 100 × 3 = 300 marks

Second question

Rakesh scored 190 and answered 70 questions correct. So his marks on 70 questions = 70 × 3 = 210

now given he scored 190

so marks deducted = 210 - 190 = 20

Here it is given every incorrect question deduct marks by 1

so questions incorrect = 20/1 = 20

So he attempted 20 questions incorrect.
