2)the product of the two digits of a number is 12.the quotient of two digits is 3
​

Answer 1

Hope the answer may help you:-

Answer 2

$Let \: one \: digit = x$

$Second \: digit = (8-x)$

$\blue{ ( \because Sum \: of \: two \:digits \:is \: 8 )}$

$Ratio \:of \: digits = 3:1 \:(given)$

$\implies \frac{x}{8-x} = \frac{3}{1}$

$\implies x = 3(8-x)$

$\implies x = 24 - 3x$

$\implies x + 3x = 24$

$\implies 4x = 24$

$\implies x = \frac{24}{4}$

$\implies x = 6$

Therefore.,

$\red{ Required \:number } \green { = 6 }$
