Farhan's father is three times as old as him.
In 12 years time, the sum of their ages will be equal to 10 times farhan's present age. Find their present ages
~~~~~~~~~~~~~~~~~~~
Let F be the Farhan's age.
Then the father's age is 3F, and the equation is
(F+12) + (3F+12) = 10F ( <<<---=== saying "In 12 years time, the sum of their ages will be equal to 10 times farhan's present age.")
4F + 24 = 10F
24 = 6F ====> F = 24/6 = 4 Farhan is 4 years old.
Then the Father is 3*4 = 12 years old.
It does not seem to be realistic . . .
It looks like that the condition is DEFECTIVE.
