Question

Find the value of p+r-q in the given magic square.

Answer 1

• First we have to find the sum.
• From the diagonal 6+7+8=21
• Now in the first row we get p+3+8=21
• So p=10
• Now, in the second row we get q+7+9=21
• So q=5
• Now in the third row we get 6+r+4=21
• So r=11
• Hence p+r-q=10+11-5=16
