Question

The ratio of two number is 7:5If the difference between these number is 12 find the number​

Answer 1

Answer:

ATQ

7x - 5x = 127x−5x=12

So , from here we can find the value of x.

\Rightarrow 7x - 5x = 12⇒7x−5x=12

\Rightarrow 2x = 12⇒2x=12

\Rightarrow x = \dfrac{12}{2}⇒x=

2

12

\Rightarrow x = 6⇒x=6

{\boxed{\therefore x = 6}}

∴x=6

______________________________________

Hence the two numbers are:

7x \rightarrow 7 × (2)7x→7×(2)

7x \rightarrow 147x→14

{\boxed{\therefore one\:number\:is\:14}}

∴onenumberis14

5x \rightarrow 5 × (2)5x→5×(2)

5x \rightarrow 105x→10

{\boxed{\therefore other\:number\:is\:10}}

∴othernumberis10

Answer 2

Answer:

let X be in the ratio

7x, 5x

according to question

7x-5x=12

2x=12

x=12/2

x=6

first no=7x=>7*6=42

second no=5x=>5*6=30
