Answer 1

Question :

Midhun's age after 10 years will be 4 times his age 8 years back. What is the present age of Midhun ?

To find :

Midhun's present age

Solution :

$\sf\small \: Let \: Midhun's \: present \: age \: be \: x \: years$

$\sf \small \:Midhun's \: age \: 8 \: years \: ago = (x - 8) \: years$

$\sf \small \: He \: will \: be \: 4 \: times = 4(x - 8)$

$\sf \small \:After \: 10 \: years \: he \: will \: be = (x + 10) \: years$

$\sf \small \: He \: will \: b e \: four \: times \: his \: age = x + 10 \times 4 = x + 40$

So now the equation is

$\sf x + 40 = 4(x - 8)$

$x + 40 = 4x - 32$

$40 + 32 = 4x - x$

$3x = 72$

$x = \frac{72}{3}$

$\boxed{x = 24}$

So we now know the value of x

So present age is x + 40 = 24 + 40 = 64 years

• Present age of Midhun is 64 years.
