Question

120 students of standard 10 were asked which game they like and from this information pie chart is prepared, observe the pie diagram and answer the questions.

1. How many students like to play Tennis? 
2. What will be central angle for Kho-Kho? 
3. How many students like Kabaddi?

Answer 1

Given: 120 students and the pie‑chart percentages: Tennis = 15%, Kho‑Kho = 13%, Kabaddi = 10%.

Step-wise calculation:

a. Number who like Tennis:

Tennis % = 15% of 120

Number = `15/100 xx 120`

= 0.15 × 120

= 18

b. Central angle for Kho‑Kho (use central angle = `"Percentage"/100 xx 360^circ`).

Kho‑Kho % = 13%

Angle = `13/100 xx 360^circ`

= 46.8°

If needed in degrees and minutes: 46.8° = 46° 48′

c. Number who like Kabaddi:

Kabaddi % = 10% of 120

Number = `10/100 xx 120`

= 0.10 × 120

= 12
