Question

The sum of two numbers is 7 and its difference 2 . What is the product of those numbers

A 45/4
B 44/5
C 43/5
D 43/4​

Answer 1

Answer:

A

Step-by-step explanation:

let two no.s be x and y

given,

x+y=7

x-y=2

adding these two equations we get

2x=9

so x=9/2

then y=5/2

Now

x.y= 9/2 X 5/2

=45/4

Answer 2

Answer:

A

Step-by-step explanation:

let the numbers be x and y

x+y = 7

let x>y x-y = 2

2x= 9

x=9/2

y=7-9/2=5/2

x*y = 45/4
