N = Total marks of student 1 in subjects 1 and 4 taken together
M = Total marks of student 2 in subjects 3 and 5 taken together
What is the value of N : M?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e 12 : 13
Given :
N = Total marks of student 1 in subjects 1 and 4 taken together
M = Total marks of student 2 in subjects 3 and 5 taken together
Now, N = 40 + 32 = 72
And M = 35 + 43 = 78
Hence the required ratio N : M = 72 : 78 = 12 : 13.
