Answer 1

Problem on Age

Step-by-step explanation:

• Let, the present age be x.
• After 20 years from now, the age will be 4 times as old as present age.
• ∵ the age will be 4 × x = 4x
• We can say that the age after 20 years is equals to x + 20
• Solving the equations
• x + 20= 4x
• 20 = 4x- x
• 3x=20        
• Present age,  $x=\frac{20}{3}$  $=6\frac{2}{3}$
• ∴ the present age is 6 years and $\frac{2}{3}$ of a year.
• $\frac{2}{3}$ of a year is equals to 8 months

The present age is 6 years and 8 months.
