1. Lion, Goat and Grass

There is a man who has a lion, a goat, and a bundle of grass. He has a boat too. He wants to cross a river with his lion, goat and bundle of grass.

But his boat is not very strong.

He can take only one thing at a time with him.

But the problem is that as you know if he takes the bundle of grass the lion will eat the goat, and if he takes the lion the goat will eat the grass. He wants to transport them safely to the other side of the river. HOW?

2. Farmer’s Reply

Afarmer was very much fond of birds and cows. One day I went to his farm. I was very much pleased to see his birds and cows. I asked him, How many birds and how many cows do you have in this farm?

The farmer replied, There are 30 heads and 100 feet. I could not understand. I looked at him surprisingly. He told me to think and find out.

Can you?

3. The Pigeon Holes

What is the largest number of pigeonholes that can be occupied by 100 pigeons if each hole is occupied, but no two holes contain the same number of pigeons?

4. Mumbai to Goa

Mohan and Dev decided to travel from Mumbai to Goa in their new car. However, since only Dev could drive they had to cover the distance in stages. On the first day, they travelled half of the total distance. On the second day, they had to travel through very hilly parts. So they could cover only half of the remaining distance. Dev was tired from all that difficult driving. So he decided to take rest on the third day and travelled only one third of the remaining distance. On the fourth day, he was fresh and covered three fourths of the remaining distance. When they finished breakfast on the fifth day they found that they had only 24 km left to reach Goa. What was the total distance between Mumbai and Goa?

5. Fair Share

Vikas has 16 chocolates. He wants to share them equally with his three friends. How many chocolates each will have?

6.Three Friends

Anand, Bipin and Chandu are three friends. They supply vegetables, fruits and meat respectively to a big hotel. Anand visits the hotel every second day, Bipin comes with his fresh load every third day, and Chandu comes every fifth day. All three of them met on the 11th of April. When would they all meet again?

7. Arab Sheikh

An Arab Sheikh tells his two sons to race their camels to a distant city to see who will inherit his fortune. He has also announced that the one whose camel is slower will be the owner of his wealth. The brothers, after wandering aimlessly for days, ask a wise man for advice. After hearing the advice they jump on the camels and race as fast as they can to the city.

What does the wise man say?

8. Anil’s Ability

Anil is a clever boy who went to spring to get exactly 4 quarts of water. But he had only two jars – one jar holding 5 quarts and the other jar holding 3 quarts. How was Anil able to get 4 quarts of water using only these jars?

9. Read the Colour

Try to read the colour of each word as fast as you can. It might be a bit tricky.

red red purple gray green green purple purple red gray gray blue blue red purple puple red gray gray red red green purple purple yellow yellow blue gray orange blue green green gray red purple orange blue blue red blue purple yellow yellow yellow blue red green gray purple.

10. The Conscientious Driver

Aunt Nellie always followed the advice to conserve energy as she was a conscientious driver. While driving her family Ford one day, she came to a stop sign and noticed that the odometer showed 25,952 miles. Observant as she was, she recognised that this number was palindromic; it read the same backward and forward. I bet you it’ll be a long time before a palindromic number happens again, Aunt Nellie said to herself. Yet, two hours later when she arrived home the odometer showed a new palindrome number.

What was the new palindromic number, and how fast was she travelling in those two hours?

11. Funny Sliding Triangles

See the figure given below. It is a figure of a big triangle which includes a lot of small triangles. Each small triangle is marked with one number. In short, this is nothing but a grid of 49 numbered triangles. If triangle numbered 1 slides vertically downwards and then horizontally to the right it could land on triangle numbered 23. By exactly the

same maneuver, which triangle would land on triangle numbered 46?

Think, try and solve.

12. Think and Solve

Think about the following three problems and try to solve them:

1. A farmer, being asked what number of animal he kept on his farm, answered: They’re all horses but two, all sheep but two, and all pigs but two. How many animals did he have in all?

2. If a turkey weighs 10 kg and a half of its own weight, what does the turkey weigh?

3. Take 45 away from 45 and leave 45 as the remainder! If you think it can’t be done, think again. Here’s one way:

987654321 = 45

– 123456789 = 45

864197532 = 45

Using the same system, can you find another way?

13. Magic Pentagon

See this figure of PENTAGON. Complete this magic pentagon so that the numbers in any radial line add up to 90. Second condition is that the number in each of the five shells total 90. Third condition is that the numbers on any spiral pathway through the shells also total 90.

Try again and again and find the required numbers in the blank circles.

14. Puzzling Turns

See the puzzling map given below. This whole map shows various streets. The problem for you is – Can you get from the North of this street map to the South by turning alternately left and right every time you come to a crossing? You can start by turning first to the left or to the right. Try and see whether you can do it.
