Question

the difference between two no is 48.the ration of two no.s is 7:3.What are the two numbers​

please tell step by step...​

Answer 1

Step-by-step explanation:

7x-3x=48

4x=48

x=48/4

x=12

verify:

7×12=84

3×12=36

Answer 2

Given :

• Difference between two numbers is 48.
• The ratio of the two numbers is 7:3.

To Find :

• Two numbers.

Solution :

$\longmapsto\tt{Let\:first\:no.\:be=7x}$

$\longmapsto\tt{Let\:second\:no.\:be=3x}$

A.T.Q :

$\longmapsto\tt{7x-48=3x}$

$\longmapsto\tt{7x-3x=48}$

$\longmapsto\tt{4x=48}$

$\longmapsto\tt{x=\cancel\dfrac{48}{4}}$

$\longmapsto\tt\bold{x=12}$

Value of x is 12..

Therefore :

$\longmapsto\tt{First\:No.=7(12)}$

$\longmapsto\tt\bold{84}$

$\longmapsto\tt{Second\:No.=3(12)}$

$\longmapsto\tt\bold{36}$

So , The two numbers are 84 , 36...
