Answer:

The present age of the boy is 5 years

Step-by-step explanation:

Let the present age of the boy be 'x'.

The question says that after 10 years, he will be 3 times his present age.

So, the equation formed will be:

x + 10 = 3x  

Now, upon solving it-

x + 10 = 3x

   10   = 3x - x  (Sign changes from +ve to -ve as 'x' moves from LHS to RHS)

   10   = 2x

  10/2 = x

    5    = x   (The age of the boy is 5 years).

Checking:

x + 10 = 3x

5 + 10 = 3 x 5

   15     = 15

The equation is satisfied with x = 5 as LHS = RHS.

Therefore, the present age of the boy is 5 years.

Hope this helps...
