Physics:
Total number of students = 300
Number of boys = 60/100 × 300 = 180
Number of girls = 300 – 180 = 120
∴ Difference between number of boys studying Mathematics and number of girls studying Physics = 150 – 120 = 30

Directions:In a University, there are 1200 students studying four diff...

Understanding the given information:
- Total number of students = 1200
- Percentage of students studying Mathematics = 20%
- Percentage of students studying Physics = 25%
- Number of students studying Statistics = 320
- Girls studying Chemistry = 3/5 of total number of Chemistry students
- Boys studying Mathematics = 150
- Boys studying Physics = 60% of total Physics students
- Girls studying Statistics = 250

Calculating the number of students in each subject:
- Number of students studying Mathematics = 20% of 1200 = 0.20 * 1200 = 240
- Number of students studying Physics = 25% of 1200 = 0.25 * 1200 = 300
- Number of students studying Chemistry = Total - (Mathematics + Physics + Statistics) = 1200 - (240 + 300 + 320) = 340
- Number of girls studying Chemistry = 3/5 * 340 = 204
- Number of boys studying Chemistry = 340 - 204 = 136

Calculating the difference:
- Number of boys studying in Mathematics = 150
- Number of girls studying in Physics = Total Physics students - Boys studying Physics = 300 - (0.60 * 300) = 300 - 180 = 120
- Difference = Boys in Mathematics - Girls in Physics = 150 - 120 = 30

Therefore, the difference between the number of boys studying Mathematics and the number of girls studying Physics is 30. So, the correct answer is option 'B' which states a difference of 30.
