Question

the sum of two numbers is 25 .one of the numbers exceeds the other by 9 .find the two numbers.

Answer 1

let the first one be x
therefore the other be (25-x)
A.T.Q.
25-x=x+9
25-9=x+x
16=2x
x=8
so,the first no=8
&snd no .=25-8
=17

Answer 2

let the no. be x and y respectively.
x+y=25......equa1
x=9+y......eq2(when x is greater than y)
y=9+x....eq3(when y is greater than x)
Now, solving equations
x=17 & y=8 (when x is greater than y)
or x=8 & y=17(when y is greater than x)
