(a) So there are a total of 210 children going.
(b) Number of seats in one bus = 50
Number of seats in 4 buses = 4×50 = 200
Thus, 200 children will get seats in 4 buses.
(c) Number of children going to the trip = 210
Number of children who will get seats = 200
So, number of children left without seats = 210 − 200 = 10

The Journey Begins
If they go to Bhimbetka, they will reach there
- Before 10 o’clock
- Between 10 o’clock and 11 o’clock
- After 11 o’clock
Answer.
Distance of Bhopal = 70 km
Distance of Bhimbetka = 50 km
They will take 2 hours to reach Bhopal.
So time take to cover 70 km = 2 hours
Time take to cover half distance, 35 km = 1 hour
So, time taken to cover 50 km will be more than 1 hour and less than 2 hours.
They started at 9 o’clock.
