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 ?
Answer & explanation
Correct answer: option 1
N = Total marks of student 1 in subjects 1 and 4 taken together
= 40 + 32
= 72
M = Total marks of student 2 in subjects 3 and 5 taken together
= 35 + 43
= 78
Ratio of N : M
= 72 : 78
= 12 : 13
