The second number is 38

Given :

• Two numbers are in the ratio 5 : 19

• The first number is 10

To find :

The second number

Solution :

Step 1 of 2 :

Form the equation to find the number

Here it is given that two numbers are in the ratio 5 : 19

Now first number is 10

Let x be the required number

By the given condition

10 : x = 5 : 19

Step 2 of 2 :

Find the second number

10 : x = 5 : 19

$\displaystyle \sf{ \implies \frac{10}{x} = \frac{5}{19} }$

$\displaystyle \sf{ \implies 5x = 190 }$

$\displaystyle \sf{ \implies x = \frac{190}{5} }$

$\displaystyle \sf{ \implies x = 38}$

The second number is 38
