If A = x^2 – y^2, B = 20 and x + y = 10, then (a) A is greater than B (b) B is greater than A (c) A is equal to B
If A = x2 – y2, B = 20 and x + y = 10, then
(a) A is greater than B
(b) B is greater than A
(c) A is equal to B
(d) It is not possible to compare A and B as the data provided is inadequate

(d) A = x2 – y2 = (x + y)(x – y) = 10 (x – y) B = 20
Now, it is not possible to compare A and B, as the value of x and y is not known.
