• Which boat gives them the most time taking the least money?

• Javed went twice for boating. He paid a total of Rs 40. and boated for 50 minutes. Which two boats did he take? _____________

Answer 1

• Money Indra and Bhanu paid for the motorboat = Rs 25 + Rs 25
= Rs 50
Money paid by them for the oar boat = Rs 15 + Rs 15
= Rs 30
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

• Money spent by the group of children for the double-decker trip = Rs 450
Price of the double-decker trip per child = Rs 30

Number of children = $\frac{\mathrm{Total}\mathrm{money}\mathrm{spent}\mathrm{for}\mathrm{the}\mathrm{double}-\mathrm{decker}\mathrm{trip}}{\mathrm{Price}\mathrm{of}\mathrm{the}\mathrm{double}-\mathrm{decker}\mathrm{trip}\mathrm{for}\mathrm{one}\mathrm{child}}$
= $\frac{450}{30}$
= 15
Now,
Number of children who went for the double-decker trip = 15

• We know
1 hour = 60 minutes
We can see from the table that the paddle boat takes 30 minutes to complete a trip.
So, the paddle boat will take 2 trips in 60 minutes.

• We know
Half an hour = 30 minutes
From the table, we can see that the motorboat takes 20 minutes to complete a trip.
So, the motor boat takes less than 30 minutes to complete a trip.

• From the table, we can see that the least money, that is, Rs 15, is charged by the paddle boat and the oar boat. Also, the oar boat trip gives more time compared to that given by the paddle boat for the same money.

• Javed went twice for boating. Money paid by him is Rs 40 and the total time spent by him is 50 minutes. From the table, we can see that Javed took the paddle boat and motorboat trips, which together cost him Rs 40. Also, the total time spent on both the boats is 50 minutes.
