Question

My father is 21 years older than me in 12 years time his age will be twice of mine how old am i now

Answer 1

Answer:-

My age is 9 years now.

Step - by - step explanation:-

Solution:-

→ Suppose my age = x years

→ My father's age =( my age + 21 years )

=( x +21 ) years

According to the question,

After 12 years ,

2 ( My age + 21 )= My father's age +12

$\implies \: \bf{2(x + 12) = (x + 21) + 12} \\ \\ \implies \: \bf{2x + 24 = x + 33} \\ \\ \implies \bf{\: 2x - x = 33 - 24} \\ \\ \bf{ \implies \: x \: = 9 \: years}$

Hence ,My age is 9 years now.

Hope it helps you.
