Question

a number is smaller then another number by 20 the sum of these number is 240.find the number​

Answer 1

Answer:

110 and 130

Step-by-step explanation:

If a number is x

then the other one is=x+20

so,x+x+20=240

2x=240-20=220

x=220/2=110

other one is 110+20=130

Answer 2

Step-by-step explanation:

$let \: the \: smaller \: no \: be \: x \\ let \: the \: bigger \: no \: be \: x + 20 \\ a.t.q. \\ x + (x + 20) = 240 \\ x + x + 20 = 240 \\ 2x = 240 - 20 \\ 2x = 220 \\ x = \frac{220}{2} \\ x = 110(ans)$

smaller no = 110

bigger no = 110 + 20 = 130
