Answer :
3700
Let the numbers be A and B
A + B = 100
A - B = 37
A = 68.5
B = 31.5
A^2 - B^2 = (68.5)^2 - (31.5)^2
= 4692.25 - 992.25 = 3700
Let the numbers be A and B
A + B = 100
A - B = 37
A = 68.5
B = 31.5
A^2 - B^2 = (68.5)^2 - (31.5)^2
= 4692.25 - 992.25 = 3700
Answer:
x + y = 100
x - y = 37
--------------
2x = 137
x = 68.5, y = 31.5
68.5² - 31.5² = (68.5 - 31.5)(68.5 + 31.5)
= 37(100) = 3,700
The correct answer is B.
