Question

What is the ratio of the total number of students studying MCA from all three institutes together to the total number of students studying M.Sc from all three institutes together?

• A. 13:22
• B. 13:23
• C. 14:23
• D. 13:24
• E. 12:23

Answer 1

The correct option is B 13:23

Total number of students studying MCA from all three institutes together = 120 + 130 + 140 = 390
Total number of students studying M.Sc from all three institutes together = 210 + 230 + 250 = 690
$\therefore$ Required Ratio $=\frac{390}{690}=\frac{13}{23}$ or $13:23$
