Question

A man is thrice as his son .After 14 years the man will be twice as old as his son then what is the present age of his son

Answer 1

$\underline { \blue{ At \:present :}}$

$Age \: of \: Son = x \: years$

$Age \: of \: a \: man = 3x \: years$

$\underline { \blue{ After\: 14 \: years:}}$

$Age \: of \: Son = (x + 14) \: years$

$Age \: of \: the \: man = ( 3x + 14 )\: years$

/* According to the problem given */

$(3x+14) = 2(x+14)$

$\implies (3x+14) = 2x+ 28$

$\implies 3x - 2x = 28 - 14$

$\implies x = 14$

Therefore.,

$\red{ Present \: age \: of \: son } \green { = 14 \: years }$

$\red{ Present \: age \: of \: the\:man }\\= 3x \\= 3\times 14 \\ \green { = 42\: years }$
