Question

the difference between two numbers is 26 and one number is three times the other .Find them

Answer 1

Let on of the numbers  be 'x'.
∴ the other number= 3x

According to the problem, 
3x-x=26
⇒ 2x=26
⇒ x=13

∴one number= x=13(ans)
∴other number=3x =39(ans)

Answer 2

$\bf\huge\boxed{\boxed{\bf\huge\:Hello\:Mate}}}$

$\bf\huge Let \:the\:number\:be\:p\:and\:y$

$\bf\huge => p - y = 26 (Eqn 1)$

$\bf\huge => p = 3y (Eqn 2)$

$\bf\huge From\:Eqn(2) => y = \frac{p}{3}$

$\bf\huge Put\:the\:value\:in\:Eqn(1)$

$\bf\huge => p - \frac{p}{3} = 26$

$\bf\huge => 3p - p = 78$

$\bf\huge => 2p = 78$

$\bf\huge => p = 39$

$\bf\huge Substitute\:p = 39 \:in\:Eqn(2)$

$\bf\huge => 39 = 3y$

$\bf\huge => y = \frac{39}{3} = 13$

$\bf\huge Required\:Number\:=\:39\:and\:13$
