Solution :

The correct option is Total boys in college R is 360.

Step-by-step Explanation:

1. Extract Data from the Chart:
From the given pie chart, we are provided with the distribution of the total number of boys across four colleges: P, Q, R, and S.
The total number of boys across all four colleges is:

Total number of boys=1200

2. Find the percentage of boys in College R:
Looking at the chart, the sector representing College R is colored green and is labeled with a percentage value of:

Percentage of boys in College R=30%

3. Calculate the number of boys in College R:
We can find the actual number of boys in College R by calculating 30% of the total number of boys (1200):

Number of boys in College R=30%×1200

Number of boys in College R=30100×1200

Number of boys in College R=30×12=360

Therefore, the statement "Total boys in college R is 360" is mathematically correct and true.
