Question

sum of 2 numbers is 15 and of the number are 10 greater than the other. find the number​

Answer 1

let the numbers be xand x+10

so

x+x+10=15

2x= 15-10

2x=5

x=2.5

and

x+10=2.5+10

=12.5

Answer 2

Answer:

Let the First number = x

and the Second number = y

According to the condition,

x=y+15\ \ \dots(i)

x+y=195\ \ \ \ \dots(ii)

Substituting the eq. (i) in eq. (ii), we will get,

x+y=195

\Rightarrow y+15+y=195

⇒2y=195-15

⇒y=\frac{180}{2}

⇒y=90

Now substituting the value of y in eq. (i), we will get

x=y+15

\Rightarrow90+15=105

∴ The two numbers are 105 and 90.
