What is the ratio of the total number of students studying in Physics to that of studying in Mathematics in all four colleges taken together?
Show answer & explanation
Correct answer: D
Explanation
The correct answer is Option 4 i.e. 776 : 603.
The total number of students studying in Physics = 420 + 435 + 412 + 285 = 1552
The total number of students studying in Mathematics = 256 + 310 + 295 + 345 = 1206
Now, required ratio = 1552 : 1206 = 776 : 603
