Question

in the matrix given below the value of a,b and c are
please explain why a​

Answer 1

9+10+11=30

9+A+12=30

21+A=30

A=30-21=9

9+B+8=30

17+B=30

B=30-17=13

8+C+11=30

19+C=30

C=30-19=11

Therefore A=9,B=13,C=11

This is the correct answer

It can't be option A

because when you add the values it is not equal to 30.
