Chapter 3: A Trip to Bhopal

Answer: The total money Indra and Bhanu paid for the motor boat = Rs 25 + Rs 25 = 50

Money paid by them for the oar boat = Rs 15 + Rs 15 = Rs 30

The total money Indra and Bhanu paid for the motorboat and the oar boat = Rs 50 + Rs 30 = Rs 80

Time for the motorboat ride = 20 minutes

Time for the oar boat ride = 45 minutes

Total time for both the rides = 20 + 45 = 65 minutes

Answer: Money spent by the group of children for the double-decker trip = Rs 450

The amount paid for the double-decker trip per child = Rs 30

The number of children who went on the double-decker trip = Total rupees paid / Ticket price per child

= Rs 450 / 30

= 15 children

Answer: We know 1 hour = 60 minutes

From the table, the paddle boat takes 30 minutes to complete a trip. Hence, the paddle boat will take 2 trips in 60 minutes, i.e., 1 hour.

Answer: We know half an hour = 30 minutes

From the table, the motorboat takes 30 minutes to complete a trip. Hence, the motorboat takes less than 30 minutes to complete a trip.

Answer: From the table, we come to know that the least money, i.e., Rs 15, is charged by the paddle boat and the oar boat. Here, the oar boat trip gives more time compared to that given by the paddle boat for the same amount. Therefore, the oar boat gives the most time taking the least money.

Answer: Javed took a paddle and motorboat.

The total money paid by him = Rs 40

The total time spent by him = Rs 50 minutes

From the table, we can see that Javed took the paddle boat and motorboat trips, which together cost him Rs 40, and the total time spent on both boats was 50 minutes.

Time to return

Practice Time

Answer: Among all the cave paintings, 8500 years is the oldest cave painting. Hence, option (c) is the correct answer.

Answer: The number of children in a bus = 48 children

The number of children three buses can carry = 48 × 3

= 144

So, there are about 150 children.

Therefore, option (c) is the correct answer.

Answer: Let us add the pairs to check the pair that has a sum greater than 500.

152 + 241 = 393

321 + 192 = 513

99 + 299 = 398

401 + 91 = 492

Therefore, 321 + 192 gives 513, which is more than 500. So, option (b) is the correct answer.
