The answer is B
89+12+9=110
100(.25)=27.5
110-27.5=82.5
He got 22/25 questions right because
if you put X as the number of questions he got right out of 25 and equal it to 88 out of 100 you can cross multiply to get X
x/25=88/100
100x=25×88
25×88=2200
100x=2200
divide 100 on both sides
therefore
2200/100= 22
