Question

four years ago asim was twice as mano now the difference in their age is 11 find manos present age​

Answer 1

Ages

Answer: Present age of Mano = 15 years  .

Explanation:

Given that

four years ago age of Asim was twice than  Mano's age.

Now that is currently difference in their ages is 11.

Need to find Mano age.

PRESENT AGE

As four years ago age of asim was greater that age of mano , so in current scenario also age of Asim is greater that Manos

so lets assume current age of Mano = x

As difference in current ages is 11  and Asim is older that Mano ,

⇒  current age of Asim = x + 11

FOUR YEARS AGO

Age of Mano four years ago = current age of Mano - 4 = x - 4

Age of Asim four years ago = current age of Asim - 4 = (x + 11 ) - 4 = x + 7

As given that four years ago age of Asim was twice than  Mano's age.

⇒ Age of Asim four years ago = 2 × Age of Mano four years ago

⇒ x+7  = 2 ×( x-4 )

⇒ x + 7 = 2x - 8

⇒ 7 + 8 = 2x - x

⇒ 15 = x

⇒ x = 15 years

So Present age of Mano  = x = 15 years  .
