Total seats (in brackets) and students admitted to four streams in four colleges.

College	Total Seats	Science	Art	Engineering	Medical
w	500	100	100	50	150
x	500	150	100	50	50
y	1000	350	300	150	50
z	1000	300	350	150	100

What is the ratio of students admitted to the science stream to those admitted to the engineering stream?

A9:4 ✓ Correct

B7:4

C11:5

D9:5

Correct answer: (A) 9:4

Explanation

The answer is 9 to 4.

The science admissions total 900.

The engineering admissions total 400.

So the ratio is 900 to 400.

Dividing both by 100 gives 9 to 4.

So the ratio simplifies to 9 to 4.

So the answer is 9 to 4.
