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 1st January 2018. This means that Ramesh’s eleventh birthday was on 31st 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, ______________

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.
