Solution:Concept- To find the values of v, x, y and z we will use the math operations one by one we will find the values of these.
We will start one by one-
(i) Given in the question we have
To find the value of x and y we will take the towards the right side of the equation.
Hence, we got the value of .
(ii) So in this question we need to find the value of z.
Hence, the value of z is 20.
(iii) Now we will calculate the value of v
So, the value of v is 5.
Hence, the correct option is 1.
