Quantitative Aptitude(IBPS CL) Case Studies

Directions: Read the passage carefully and answer the following questions:

In three different colleges, there are three branches Mechanical Engineering, Civil Engineering and Electrical Engineering. The total number of students in college B is 760. The number of students in Mechanical Engineering in college B is 300. The number of students in Electrical Engineering in college C is twice than the number of Mechanical Engineering in the same college. The number of students in Mechanical Engineering in college B is 60% of the students in number of students in same branch in college A. The number of Civil engineering is half the number of Mechanical engineering in college A and 50 more than the number of students in Electrical Engineering from college C. The total number of students in Civil Engineering in college B is 160 more than the number of students in Electrical Engineering in college C. The total number of students in Civil Engineering in all the colleges together is 750. The number of students in Electrical Engineering in college A is 50% more than the number of students in same branch in college B.

Explanation:

Correct option 2: 300

Given
The number of students in Mechanical Engineering in college B is 300 and The number of students in Mechanical Engineering in college B is 300.
.. The number of students in Mechanical Engineering = 500
Now,
The number of students from Civil engineering is half the number of Mechanical engineering in college A and 50 more than the number of students in Electrical Engineering from college C.
.. The number of students from Civil engineering in college A = 250
Also, the number of students in Electrical Engineering from college C = 200
The total number of students in Civil Engineering in college B is 160 more than the number of students in Electrical Engineering in college C.
.. The total number of students in Civil Engineering in college B = 200 + 160 = 360 The total number of students in Civil Engineering in all the colleges together is 750.
.. The total number of students in Civil Engineering = 140
The total number of students in college B is 760
.. Number of students of electrical in college B = 760-300-360 = 100
.. Number of students in electrical from college A = 150% of 100 = 150
