How much can you drink? — Page 139Chapter opener — Chintu at the sugarcane juice stall
Q1Why do you think Chintu does not take the challenge?The small glass Chintu means and the bigger glass the stall uses.
Answer
Because the stall’s glasses are much bigger.
Chintu can drink 6 of his own small glasses.
One big glass holds far more juice than one small glass.
So 6 big glasses are too much for him.
Q2Do you think you can take the challenge?The small glass Chintu means and the bigger glass the stall uses.
Answer
No, I cannot drink 6 big glasses of juice.
One big glass already fills my stomach.
Six of them are a very large amount of juice.

Tricky balls — Page 149Montu’s puzzle with three balls and a pan-balance
Q1Montu poses a puzzle to his friends: 3 balls look similar in size. One of them is heavier and 2 balls are equal in weight. You have only a pan-balance and no weights. Using the 3 balls and the pan-balance, can you identify which is the heavy ball?Three balls that look the same, and the pan-balance with both pans empty.
Answer
Yes, we can find the heavy ball.
Put one ball on each pan. Keep the third ball aside.
If one pan goes down, that ball is the heavy one.
If the pans stay level, the ball kept aside is the heavy one.
Q2(a) How many times will you have to weigh?Three balls that look the same, and the pan-balance with both pans empty.
Answer
Only 1 time.
One weighing already tells us the answer.
We do not need a second turn.
Q3(b) Use the balance only one time and tell which is the heavy ball.Three balls that look the same, and the pan-balance with both pans empty.
Answer
Call the balls A, B and C. Put A and B on the two pans. Keep C aside.
If A’s pan goes down, A is the heavy ball.
If B’s pan goes down, B is the heavy ball.
If the pans stay level, C is the heavy ball.
Q4There are three same-sized balls of different weights and colours: red, orange and green. You can use the pan-balance for it but cannot use weights. How will you find which one is the heaviest and which one is the lightest?The red, orange and green balls, and the pan-balance with both pans empty.
Answer
Weigh two balls at a time.
Weigh the red and orange balls. Keep the heavier one.
Weigh it with the green ball. The ball whose pan goes down is the heaviest.
Weigh the other two balls. The ball whose pan goes up is the lightest.
