The Correct Option is C
Solution and Explanation
The correct answer is (C):
Given, ratio of the scores of Amal and Bimal is 11 : 14.
Let 11x and 14x be the scores of Amal and Bimal.
Let a be the score which is increased.
⇒ 11x+a/14x+a = 47/56
616x+56a = 658x + 47a
9a = 42x
a = 42x/9
Required ratio = (14x+42x/9):14x
= (1+1/3):1
= 4:3

- In a small college, students are allowed to take only one specialization. Traditionally, only two specializations are offered: Science and Arts. Students enrolled to specialize in Science must take Physics and Mathematics subjects, while students enrolled to specialize in Arts must take Economics and Political Science subjects. Students enrolled in Science are not allowed to take either Economics or Political Science, while students enrolled in Arts are not allowed to take either Physics or Mathematics.
Recently, the college has started a third specialization called MatEco that requires students to take Economics and Mathematics. However, MatEco students would not be allowed to take either Physics or Political Science. When the college opens this new specialization for enrolment, it allows students, originally enrolled in Science or Arts, to switch to MatEco.
From among the students originally enrolled in Arts, 20 students switch to MatEco. This makes the number of Science students twice the number of Arts students. After this, from among the students who originally enrolled in Science, 45 students switch to MatEco. This makes the number of Arts students twice the number of Science students.
In total, how many students, from among those originally enrolled in Science or Arts, are now taking Economics?- XAT - 2024
