Mathematics is a subject that children often dread or find boring. However, maths does not have to be dull or intimidating. It can be a lot of fun if taught the right way. Here are 20 mathematical riddles for kids that will help children improve their maths skills in an interesting and enjoyable way.

## Easy Maths Puzzles with Answers for Children

**1.** Ramesh turned 10 years old day before yesterday. By next year he will become 13. How is this possible?

**Answer: **This is one of the more amusing maths puzzles for kids age 6. With the help of math and a calendar, this puzzle can be easily explained.

For this puzzle to work, we need to assume that today is 1^{st} January 2018. This means that Ramesh’s eleventh birthday was on 31^{st} December 2017. Day before yesterday, he was 10 years old, today he is 11. By the end of the current year, 2018, he will be 12 years old. And so, by the next year (i.e. in 2019), he will be 13 years old.

**2.** What is the following number? 18, 21, 24, 27, 30, 33, 36, ______________

**Answer:** Here the pattern to be observed is: every successive number is greater by 3. So the sequence will be: 18, 21, 24, 27, 30, 33, 36, 39, 42, 45, 48, and so on.

**3.** What is the following number? 53, 51, 49, 47, 45, 43, _______________

**Answer:** Here the pattern to be observed is: every successive number is smaller by 2. So the sequence will be: 53, 51, 49, 47, 45, 43, 41, 39, 37, 35, and so on.

**4.** Hari had 6 siblings who were born all born 2 years apart. The youngest is Richa who is only 7 years old while Hari is the oldest. What is Hari’s age?

**Answer: **Richa, the youngest sibling is 7 years old. Each sibling was born 2 years apart, and there are total seven children (Hari and his 6 siblings). So Hari’s age is: 7 + 2 + 2 + 2 + 2 + 2 + 2 = 19.

**5.** Ravi used to live in a village that was next to the forest. One day he crossed paths with a genie. The genie was in a generous mood and granted Ravi one wish. Ravi, thinking it was a joke, wished for a 100 grams of gold. The genie agreed and behold! Ravi had a kilo of gold. Shocked and feeling upset that he asked for so little, Ravi requested the genie if he could ask for another wish. The genie agreed but only on one condition. The genie would come back next month on any date and Ravi would need to present him with gold rings. However, the gold rings had to be the same weight as the date on which he arrived. This means that if the genie came on the 20^{th}, he would need 20 grams of gold. What did Ravi do next?

**Answer: **This is a challenging **math riddle for kids** as the date is unknown. If Ravi decided to make a different gold ring for each day, it will become problematic. This is because he only has a 100 grams of gold. So, if he made a gold ring of 31 grams,30 grams, 29 grams and 27 grams, he would run out of gold. The solution is to make just 5 rings of weight 1 gram, 2 grams, 4 grams, 8 grams and 16 grams. This can be used in combination to reach the number 31. For example:

- 24
^{th}day: 16+8 - 13
^{th}day: 8+4+1 - 7
^{th}day: 4+2+1

**6.** If Radha is the 50^{th} fastest and slowest runner in her school, how many students are there in her school?

**Answer: **99 students.

- 50
^{th}Fastest Calculation: If you count in sequence from 1, Radha comes 50. - 50
^{th}Slowest Calculation: If you count in sequence from 99, Radha is again 50.

**7. **Wolves and Lambs Puzzles: Six Wolves can catch just six lambs in six minutes. So how many wolves will they need to catch 60 lambs in sixty minutes? Hint – the answer is not sixty.

**Answer:** 1 wolf can catch 1 lamb in six minutes. In 60 minutes, each wolf can catch 10 lambs. So, each wolf can catch ten lambs, and in sixty minutes, 6 wolves can catch 60 lambs. Another method – Six Wolves. How? 6 wolves can catch six lambs in 6 minutes. If you multiply it by ten, the same wolves can catch sixty lambs in 60 minutes.

**8. **How Many Cycles? This is another mathematical statement problem which can be solved using logic and arithmetic. Last weekend, Jack went to play in the park near his house. He rode the new bicycle gifted by his grandma on his birthday. After reaching the park, Jack saw that there were 14 tricycles and bicycles. If there were totally 38 wheels, how many tricycles were there in the park?

**Answer:** There were 10 Tricycles. There were 14 cycles in all, and all of them have at least 2 wheels. So, 14 x 2 = 28. Now there are 38 wheels totally, which means 38 – 28 = 10. So, this means there are 10 cycles with one extra wheel each, meaning 10 tricycles in all.

**9.** The principal is constructing a square playground for the children of her school. She wanted to fence the area with four exits around the playground so that the ground was accessible from all sides. If she used 27 poles on each side of the playground, how many poles would be needed in total?

**Answer: **104 poles. The 4 corner poles will be common to two sides. Hence: (25 poles x 4 sides) + 4 corner poles= 104 poles

**10. **Monkey and Bananas: Another word problem that is fun for kids to solve. Assume there are, five monkeys and each one takes 5 minutes to eat 5 bananas. How many minutes would 4 monkeys take to eat 4 bananas? Again, how many monkeys would eat 30 bananas in 30 minutes?

**Answer:** Each monkey eats 5 bananas in 5 minutes, so 1 banana in 1 minute. So, if there are 4 monkeys and 4 bananas, they will take 1 minute only. On the other hand, if 30 bananas are being eaten in 30 minutes (i.e. 1 banana in 1 minute), this is the job of one monkey.

**11.** What weighs more – A kilo of apples or a kilo of feathers?

**Answer:** They weigh the same. Each weighs exactly a kilo.

**12.** Using only addition, how can you add eight 8’s to get the number 1,000?

**Answer:** 888 + 88 + 8 + 8 + 8 =1,000

**13.** The ages of a father and son add up to 66. The age of the dad is the age of the son reversed. How old could they be?

**Answer:** There are three different answers for this: the father and son could be 51 and 15 years or 42 and 24 years old or 60 and 06 years old.

**14.** A genetic scientist engineered a new plant which could double its size every day. He made it grow in a circular pond with a circumference of 600 metres. If he planted it in the southern part of the pond, and the plant covered half the pond in 28 days, how many days would it take to cover the full pond?

**Answer: **29 days. As mentioned in the beginning, the plant doubles in size every day.

**15.** If there are four apples and you take away three, how many do you have?

**Answer: **You took the apples so obviously you have three.

**16.** How many 9’s are there between 1 and 100?

**Answer: **20. They are 9,19,29,39,49,59,69,79,89,90,91,92,93,94,95,96,97,98,99

**17.** Draw a line. Without touching it, make this line shorter.

**Answer:** Draw a longer line next to it. This will make the first line seem shorter.

**18.** There are 2 buckets, a 5 litre and a 3-litre bucket. Fill the 5-litre bucket with 4 litres of water using just these two buckets to measure.

**Answer: **Fill the 5-litre bucket fully. Pour it into the 3-litre bucket until it is full. Empty the 3-litre bucket. Pour the remaining 2 litres into the 3-litre bucket. Fill the 5-litre bucket completely. Finish filling the 3-litre bucket. Now the 5-litre bucket is left with exactly 4 litres of water.

**19.** What do the numbers 88, 96 and 11 all have in common?

**Answer:** They look the same upside down and right side up.

**20.** Two fathers and two sons go fishing. Each of them catches one fish. So why do they bring home only three fish?
