Answer 2

1] let the lowest marks be=x

2x+7=87

then x=40

2] total questions=15

Max marks one can get if all questions are correct=15*4=60

wrong answers he got=6

marks lost= -12

his total marks are 60-12= 48

3] 1hr = 1/3 part

11/5 hr=x

x=11/15 parts

4] -9+12*-1+3*3+12

as per bodmas multiply first

-9-12+9+12=0

5] angle sum property states all angles added up = 180 degrees

180-36.5-44.5= third angle

x= 180-81

x= 99 degrees
