Number of students studying Physics = ¼ × Total number of students
⇒ ¼ × 1200 = 300 students
Number of boys studying in physics = 60% of number of students studying Physics
⇒ 60/100 × 300 = 180 boys
Number of boys studying Statistics = Total number of students studying Statistics – Number of girls studying Statistics
⇒ 320 – 250 = 70 boys
∴ Total number of boys studying Statistics and Physics = 180 + 70 = 250 boys

Total Number of Students
- The total number of students studying the four different subjects is given as 1200.
Number of Students Studying Mathematics
- 20% of the total number of students are studying Mathematics.
- Therefore, the number of students studying Mathematics is 20% of 1200, which is 0.20 * 1200 = 240.
Number of Students Studying Physics
- One-fourth of the total number of students are studying Physics.
- Therefore, the number of students studying Physics is one-fourth of 1200, which is 1/4 * 1200 = 300.
Number of Students Studying Statistics
- The number of students studying Statistics is given as 320.
Number of Girls Studying Chemistry
- Three-fifths of the total number of students studying Chemistry are girls.
- Let the total number of students studying Chemistry be x.
- Therefore, the number of girls studying Chemistry is 3/5 * x.
Number of Boys Studying Mathematics
- The number of boys studying Mathematics is given as 150.
Number of Boys Studying Physics
- 60% of the students studying Physics are boys.
- Therefore, the number of boys studying Physics is 60% of 300, which is 0.60 * 300 = 180.
Number of Girls Studying Statistics
- The number of girls studying Statistics is given as 250.
Total Number of Boys Studying Statistics and Physics
- To find the total number of boys studying Statistics and Physics, we need to add the number of boys studying Statistics and the number of boys studying Physics.
- The number of boys studying Statistics is not directly given, but we can find it by subtracting the number of girls studying Statistics from the total number of students studying Statistics.
- Therefore, the number of boys studying Statistics is 320 - 250 = 70.
- The total number of boys studying Statistics and Physics is 70 + 180 = 250.
Therefore, the correct answer is option C) 250.
- The total number of students studying the four different subjects is given as 1200.
Number of Students Studying Mathematics
- 20% of the total number of students are studying Mathematics.
- Therefore, the number of students studying Mathematics is 20% of 1200, which is 0.20 * 1200 = 240.
Number of Students Studying Physics
- One-fourth of the total number of students are studying Physics.
- Therefore, the number of students studying Physics is one-fourth of 1200, which is 1/4 * 1200 = 300.
Number of Students Studying Statistics
- The number of students studying Statistics is given as 320.
Number of Girls Studying Chemistry
- Three-fifths of the total number of students studying Chemistry are girls.
- Let the total number of students studying Chemistry be x.
- Therefore, the number of girls studying Chemistry is 3/5 * x.
Number of Boys Studying Mathematics
- The number of boys studying Mathematics is given as 150.
Number of Boys Studying Physics
- 60% of the students studying Physics are boys.
- Therefore, the number of boys studying Physics is 60% of 300, which is 0.60 * 300 = 180.
Number of Girls Studying Statistics
- The number of girls studying Statistics is given as 250.
Total Number of Boys Studying Statistics and Physics
- To find the total number of boys studying Statistics and Physics, we need to add the number of boys studying Statistics and the number of boys studying Physics.
- The number of boys studying Statistics is not directly given, but we can find it by subtracting the number of girls studying Statistics from the total number of students studying Statistics.
- Therefore, the number of boys studying Statistics is 320 - 250 = 70.
- The total number of boys studying Statistics and Physics is 70 + 180 = 250.
Therefore, the correct answer is option C) 250.
