Question

two numbers are in the ratio 7:2 if they differ by 20 then find the numbers​

Answer 1

Answer:

Let the numbers be 7x and 2x

According to question

7x - 2x= 20

5x= 20

x= 20/5

x= 4

Therefore,

the numbers will be (7x4)= 28 and (2x4)= 8

Answer 2

Step-by-step explanation:

$let \: x \: and \: x - 20 \: be \: the \: two \: numbers \\ \frac{x}{x - 20} = \frac{7}{2} \\ 7x - 140 = 2x \\ 7x - 2x = 140 \\ 5x = 140 \\ x = 28$
