Given information:
Chaitra is 6 years old.
Her sister is twice as old as her.
Calculating the age of Chaitra's sister:
Since her sister is twice as old as Chaitra, we can calculate her sister's age as follows:
Chaitra's age = 6 years
Sister's age = 2 * Chaitra's age
Sister's age = 2 * 6 years
Sister's age = 12 years
Calculating the age difference:
To find out how old Chaitra's sister will be when Chaitra is 50, we need to calculate the age difference between them.
Age difference = Chaitra's age when she is 50 - Chaitra's current age
Age difference = 50 years - 6 years
Age difference = 44 years
Calculating Chaitra's sister's age when Chaitra is 50:
To find out how old Chaitra's sister will be when Chaitra is 50, we add the age difference to Chaitra's sister's current age.
Sister's age when Chaitra is 50 = Sister's age + Age difference
Sister's age when Chaitra is 50 = 12 years + 44 years
Sister's age when Chaitra is 50 = 56 years
Conclusion:
When Chaitra is 50 years old, her sister will be 56 years old.
Therefore, the correct answer is option a) 56.
