Question

The sum of two natural number is 25 and their difference is 7. The numbers are
a. 17 and 8 b. 16 and 9 c. 18 and 7 d. 15 and 10​

Answer 1

The numbers are 9 and 16.

$\boxed{\fcolorbox{red}{pink}{ The numbers are 9 and 16.}}$

Let the number bex

thus

one no is x

second no is x+7

therefore x+x+7=25

2x+7=25

2x=25-7

2x=18

x=18=2

x=9

so one no is 9

another 9+7

Answer 2

From the above question we found that:

let one of the no. be x and second no. be y

so,

According to question

x+y = 25. _______(i)

x-y = 7. ________(ii)

add equitation i and ii we get,

2x = 32

x = 16

put x in i equitation. ...

y = 9

So, option b. is correct.

I hope this help you dear...❤❤❤❤
