Answer

1440 people

The correct answer is 1440 people — Subtract this from the total population: $2400 - 960 = 1440$ people belong to other groups.

Step-by-step solution

Calculate the number of Scheduled Castes: $0.18 \times 2400 = 432$ people.
Calculate the number of Scheduled Tribes: $0.22 \times 2400 = 528$ people.
Add SC and ST: $432 + 528 = 960$ people.
Subtract this from the total population: $2400 - 960 = 1440$ people belong to other groups.
