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

Similar Defence Doubts

DIRECTIONS: Read the following passage carefully and answer the questions given below it.Educational planning should aim at meeting the educational needs of the entire population of all age groups. While the traditional structure of education as a three-layer hierarchy from the primary stage to the university represents the core, we should not overlook the periphery which is equally important. Under modern conditions, workers need to rewind, or renew their enthusiasm, or strike out in a new direction, or improve their skills as much as any university professor. The retired and aged have their needs as well. Educational planning, in other words, should take care of the needs of everyone. Our structures of educational have been built upon the assumption that there is a terminal point of education. This basic defect has become all the more harmful today. A UNESCO report entitled ‘Learning to Be’ prepared by Edgar Faure and others in 1973 asserts that the education of children must prepare the future adult for various forms of self-learning. A viable education system of the future should consist of modules with different kind of functions serving a diversity of constituents. And performance, not the period of study, should be the basis for credentials. The writing is already on the wall. In view of the fact that the significance of a commitment of lifelong learning and lifetime education is being discussed only in recent years even in educationally advanced countries, the possibility of the idea becoming an integral part of educational thinking seems to be a far cry. For, to move in that direction means so much more than some simple rearrangement of the present organisation of education. But a good beginning can be made by developing Open University programmes for older learners of different categories and introducing extension services in conventional colleges and schools. Also, these institutions should learn to cooperate with numerous community organisations such as libraries, museums, municipal recreational programmes, health services etc.Q. In the context of the passage, what is the meaning of the sentence “The writing is already on the wall”?
