Shika’s mother is thrice as old as she is now. After 10years, her age will be twice shika’s age. What are their ages now?
Answers
Answer:
10
Step-by-step explanation:
shikas age be x
mothers age be 3x
10 years after shikas age is x+10
mothers age is 3x+10
3x+10=2(x+10)
3x+10=2x+20
x=10
Answer:
Shika's present age is 10 years and her mother's present age is 30 years.
Step-by-step explanation:
Let the present age of Shika be 'x'
and the present age of her mother be 'y'
Then, according to the question,
y = 3x --(i)
After 10 years,
The age of Shika = x + 10
The age of Sikha's mother = y + 10
and According to the conditions,
y + 10 = 2 (x + 10)
=> y + 10 = 2x + 20
=> y - 2x = 10 --(ii)
Substituting the value of y from equation (i) in equation (ii)
3x - 2x = 10
=> x = 10
Now, substituting this in equation (i)
=> y = 3 * 10
=> y = 30
Therefore, Shika's present age is 10 years and her mother's present age is 30 years.
