1] The sum of two numbers is 25 and their difference is 13.Find their product
a]111  b]112  c]113  d]114

let the numbers be x and y
x + y = 25
x - y = 13
-------------
2x  = 38
x = 19

x - y = 13
19 - y = 13
y = 6

product of two numbers x * y = 19 * 6 = 114

2] the difference between two numbers is 114 and their sum is 20.what is their product?
a]51  b]52  c]53  d]54

3] If the sum of two numbers is 97 and their difference is 37.Their product is
a]2011  b]1120  c]1013  d]2010
