Question

the difference between two number is 100 one number is between 90 and 100. the other is between 190 and 200what are two possible number​

Answer 1

Answer:

191-91=100

Step-by-step explanation:

1. let the no be = a-b=100
2. first no will be more than 191 and less than 200
3. second no will be more than 90 and less than 100
4. it will be any no =91,92,93...100 and 191,192,193...200
5. so 191-91=100

Answer 2

Step-by-step explanation:

Let one number be x, and the other number be y.

x and y

Their sum = 100

x + y = 100

Their difference = 6

x - y = 6

We have a pair of simultaneous equations and will solve these using substitution.

x + y = 100 (1)

x - y = 6 (2)

Rearrange (2):

x - y = 6

x = 6 + y (3)

Substitute (3) into (1)

x + y = 100

(6 + y) + y =100

6 + y + y = 100

2y = 94

y =47 (4)

Substitute (4) into (3)

x = 6 + 47

x = 6 + 47 = 53

Hence the two numbers are 47, and 53.
