Answer:
x= 14 sahils age and mothers age = 42
- Present age of Sahil = 14 years.
- Present age of Sahil's mother = 42 years.
Given :–
- The present age of Sahil's mother is three times of the Sahil's age.
- After 5 years, sum of their ages = 66 years.
To Find :–
- Present age of their ages (Sahil and his mother).
Solution :–
Let,
The age of Sahil be x.
The age of his mother be 3x because his mother is three times of the Sahil's age. [Given]
According to the given condition,
After 5 years,
• The age of Sahil = x + 5.
• The age of his mother = 3x + 5.
Sum of their ages is 66.
So,
→ (x + 5) + (3x + 5) = 66 ––––(1)
Now, we need to find the value of x.
So,
→ x + 5 + 3x + 5 = 66
→ x + 3x + 5 + 5 = 66
→ 4x + 10 = 66
→ 4x = 66 – 10
→ 4x = 56
→ x =
→ x = 14
Now, we have to find their ages.
Sahil's age = x = 14 years.
His mother's age = 3x = 3 × 14 = 42 years.
Hence,
The present age of Sahil = 14 years.
The present age of Sahil's mother = 42 years.
Verification :–
Substitute their ages in equation (1),
→ (x + 5) + (3x + 5) = 66
- x = 14.
- 3x = 42.
→ 14 + 5 + 42 + 5 = 66
→ 19 + 47 = 66
→ 66 = 66
