====================================
• Let Pandit's sister's present age be 'x'.
[] 1 year ago,
Pandit's sister's age = x - 1
Pandit's age = 3(x - 1) = 3x - 3
[] At present,
Pandit's sister's age = x - 1 + 1 = x
Pandit's age = 3x - 3 + 1 = 3x - 2
[] After one year,
Pandit's sister's age = x + 1
Pandit's age = 3x - 2 + 1 = 3x - 1
[] But, according to the question, after one year, Pandit will be twice his sister's age.
=> 3x - 1 = 2(x + 1)
=> 3x - 1 = 2x + 2
=> 3x - 2x = 2 + 1
=> x = 3
[] So, Pandit's sister's present age = x = 3 years.
[] And, Pandit's present age = 3x - 1 = 3 × 3 - 2 = 9 - 2 = 7 years.
[] Now, 5 years after,
Pandit's sister's age = 3 + 5 = 8 years.
Pandit's age = 7 + 5 = 12 years.
