A) 7
B) 25
C) 49
D) 129
Correct Answer: B
Solution :
We have\[{{(16-6)}^{2}}+{{(5-2)}^{2}}={{10}^{2}}+{{3}^{2}}=109,\] \[{{(22-15)}^{2}}+{{(21-19)}^{2}}={{7}^{2}}+{{2}^{2}}=53.\] So, missing number \[={{(17-13)}^{2}}+{{(51-48)}^{2}}={{4}^{2}}+{{3}^{2}}=25.\]You need to login to perform this action.
