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...
