A) 40
B) 44
C) 80
D) 88
Correct Answer: A
Solution :
Let two numbers be A and B. Then, A + B = 22 and \[{{A}^{2}}+{{B}^{2}}=404\] We know that \[{{(A+B)}^{2}}={{A}^{2}}+{{B}^{2}}+2AB\] Or \[{{(22)}^{2}}=404+2AB\] Or \[484=404+2AB\] Or \[2AB=80\] Or \[AB=40\] The product of the two numbers = 40You need to login to perform this action.
