Question

The age of father is 5 times of the son.After 20 years father age is 40 then what will be the age of the son

Answer 1

ANSWER :

→ Consider the age of the son as x

→ Father = 5x

→ Son = x

→ After 20 years =

→ Father = 40 years ( 5x + 20 )

→ Son = x + 20

→ Age of son =

$=>5x + 20 = 40$

$=>5x = 20$

$=>x = \frac{20}{5}$

$=>x = 4$

$\large{\green{\boxed{\green{\boxed{\red{\textsf{Son's present age = 4 years old }}}}}}}$

→ Father's current age :

$=> 5x$

$=> 5 \times 4$

$=> 20$

$\large{\green{\boxed{\green{\boxed{\red{\textsf{Dad's present age = 20 }}}}}}}$

→ Son's age after 20 years =

$=> x + 20$

$=> 4 + 20$

$=> 24$

$\small{\green{\boxed{\green{\boxed{\red{\textsf{Age of the son after 20 years = 24}}}}}}}$

∴ Son's present age = 4

∴ Son's age after 20 years = 24

∴ Father's present age = 20

∴ Father's age after 20 years = 40
