Answer:
36. Option B.
37. Option E.
38. Option C.
39. Option C.
40. Option A.
Step-by-step explanation:
From the given diagram it is clear that the middle term is the difference between sum of left column and sum of right column.
Left column [tex]=4+5+9=18[/tex]
Right column [tex]=3+6+7=16[/tex]
Middle term [tex]=18-16=2[/tex]
Similarly,
[tex](1+8+4)-(6+1+2)=4[/tex]
Now using same pattern, we can solve each question.
In ques 36,
Middle term = [tex](5+4+1)-(2+1+0)=7[/tex]
Option B is correct.
In ques 37,
Middle term = [tex](7+0+4)-(6+2+2)=1[/tex]
Option E is correct.
In ques 38,
Let missing number be x.
[tex](x+9+7)-(7+6+5)=6[/tex]
[tex]x+16-18=6[/tex]
[tex]x-2=6[/tex]
[tex]x=6+2=8[/tex]
Option C is correct.
In ques 39,
Middle term = [tex](8+7+3)-(5+2+8)=3[/tex]
Option C is correct.
In ques 40,
Let missing number be y.
[tex](7+1+8)-(3+6+y)=5[/tex]
[tex]16-9-y=5[/tex]
[tex]7-5=y[/tex]
[tex]2=y[/tex]
Option A is correct.
