✒Given : -

The present age of John's father is 10 years more than twice the present age of John...

After 10 years, age of John's father will be twice the John's age...

✒To Find : -

Current ages = ?

✒Let ,

Present age of John's be = y

Then, Present age of his father will be = 2y + 10

✒After 10 years : -

John's age = y + 10

His father's age = 2y + 10 + 10

✒Now ,

${ \large{ \bold{ \underline{ \underline{ \purple{According\:to\:the\:Question:-}}}}}} </p><p>$

$\dashrightarrow\sf{2y+10+10=2(y+10)+10}$

✒On Substituting Values : -

$\dashrightarrow\sf{2y+20=2y+20+10}$

$\sf⇢2y−2y=30−20$

$\leadsto\sf{{ \large{ \boxed{ \bold{ \bold{ \red{y=10}}}}}}}$

✒Therefore , Value of y is 10 ..

✒So ,

$</p><p>\dashrightarrow\sf{Present\:age\:of\:John(y)=10\:years}$

$\dashrightarrow\sf{Present\:age\:of\:his\:Father=2y+10}$

$\dashrightarrow\sf{2(10)+10}</p><p>$

$\dashrightarrow\sf{20+10}$

$\leadsto\sf\bold{30\:years}$

☃️Done !!
