Answer 1

Answer:

first number is 48

second number is 12

Answer 2

Given

• A number is 4 times to second number.
• The sum of these numbers is 60.

⠀

To find

• The required numbers.

⠀

Solution

• Let the first number be x.
• Then the other number will be 4x.

⠀

$\: \: \: \: \: \: \: \: \: \:\underline{\sf{\red{Sum\: of\: numbers\: is\: 60}}}$

⠀

$\tt:\implies\: \: \: \: \: \: \: \: {x + 4x = 60}$

⠀

$\tt:\implies\: \: \: \: \: \: \: \: {5x = 60}$

⠀

$\tt:\implies\: \: \: \: \: \: \: \: {x = \dfrac{60}{5}}$

⠀

$\bf:\implies\: \: \: \: \: \: \: \: {x = 12}$

⠀

• Now,

$\: \: \: \: \: \: \: \: \: \:\underline{\sf{\red{By\: putting\: the\: values}}}$

⠀

$\: \: \: \: \: \: \: \: \bullet\bf\: \: \: {First\: number = x = 12}$

$\: \: \: \: \: \: \: \: \bullet\bf\: \: \: {Second\: number = 4x = 48}$

⠀
