1.
In the given wheel, there are three sectors A, B and C. So, when we spin the wheel, the possible outcomes are A, B or C.
2.
Even prime number = 2
∴ Probability = \(\frac{1}{2}\).
3.
Blue ⟶ 1800.
4.
144° - 108° = 36°
5.
Central angle for sector B
= \(\frac{40}{100}\times\) 360° = 144°.
6.
Total number of students = 7 + 8 + 4 + 9 + 2 = 30.
7.
Required number = 2 + 16 + 14 + 4 + 6 + 14 + 8 + 10 = 74.
8.
Frequency of class 20-25 = 20.
Frequency of class 30-35 = 20
∴ Difference = 20-20 = 0.
9.
Size = 20 - 15 = 5.
10.
The height of the bar corresponding to Social Science is minimum.
11.
Total expenditure
= (1 + 6 + 4 + 5 + 2 + 3) x 1000
= Rs 21000.
12.
Expenditure done on conveyance
= 6 x 1000 = RS 6000
Expenditure done on rent = 4 x 1000
= Rs 4000
∴ Difference = Rs 6000 - Rs 4000
= Rs 2000.
13.
The height of the bar corresponding to servant's salary is minimum.
14.
