Answer 1

The correct option is (C)

You may check it by putting values of.
X= 24

y= 9

z= 5

---------------------------------
Now, How i get it⤵⤵⤵

I have taken 1st given equation.

1/3(x+y)+ 2z= 21

Now, if you see all options [other than (c)]
You observe that (x+y) is not complete devisible by 3

Hence, we can't get LHS=RHS.

Only C option is satisfying the equation

====================
Hope you get it :)
