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.
Hope it helps dear friend ☺️✌️✌️✌️
