If the sum of two numbers is 22 and the sum of their squares is 386, then the product of the numbers is  Choose the correct answer:	A) 40	B) 49	C) 80	D) 88	E) 90

Rationale: "sol . let the numbers be x and y . then , ( x + y ) = 22 and x 2 + y 2 = 386 . now , 2 xy = ( x + y ) 2 - ( x 2 + y 2 ) = ( 22 ) 2 - 386 = 484 - 386 = 98 xy = 49 . answer b"
Answer: B
