2 points for every correct answer means for one correct answer he will score 2 points

9 correct answers means 2+2+2+2+2+2+2+2+2=18 points scored by Riyaz for answering the questions right

Now, 18-a=15

a=18-15

a=3

He got 3 answers wrong

That's why his final point is less than 18. it's 15

Bro/Sis, hope you understood the concept? if not ask me again.
