Given: Ratio of number of days Ankur, Ankit and Karan worked = 4 : 3 : 2
Calculation: Let the number of days Ankur, Ankit and Karan worked be 4x, 3x and 2x respectively
⇒ Work done by Ankur in 4x days =
() ⇒ Work done by Ankit in 3x days =
() ⇒ Work done by Karan in 2x days =
() Total work done by Ankur, Ankit and Karan = 1
⇒
() +
() +
() = 1
⇒
[] = 1

⇒ x = 2
Ankur worked for 8 days [i.e. 4 × 2]
Ankit worked for 6 days [i.e. 3 × 2]
Karan worked for 4 days [i.e. 2 × 2]
∴ Required difference = 8 – 6
⇒ 2 days
