I can't take photo, so I'll write the answer here .
ans : 2 ( i think)
Working: 60% of 90 is 54
50% of 90 is 45
54 - 45 = 9
10 - 9 = 1
1+1=2
Explanation : To find the number of points they each had for the first 90 questions, multiply percentage by number of questions.
Person A have 9 points more than Person B as shown is working above. To ENSURE he can win, he needs to have 2 more points so that he will not tie or lose JUST IN CASE Person B gets all 10 points for last 10 questions .
So i think answer should be 2
Hope This Helps :)
