### How to Solve Math Puzzles?

The following are basic tips & tricks to solve the math puzzles.

• Observe the given question carefully.
• Check the numbers, patterns of the puzzle.
• Imagine the concept of the puzzle and the way of the puzzle theme is given.
• Apply the arithmetic operations i.e., addition, subtractions, multiplication, division, and also square roots, etc., and the chances to the given conditions of the number puzzle.
• The operation that satisfies the given conditions is the answer to the puzzle.

Question 1:
Ramu has to distribute 19 sheep among 3 brothers in such a way that the eldest gets half of all the cows, the middle brother gets one fourth and the youngest one gets fifth. But no sheep should be left.
Solution:
Ramu has to borrow one sheep from any one person.
The total number of sheep becomes 19 + 1 = 20
As, stated eldest brother gets 1/2 of 20 sheep = 10 sheep
Middle brother gets 1/4 of total sheep = 1/4 x 20 = 5 sheep
Youngest brother gets 1/5 of total sheep = 1/5 of 20 = 4 sheep
The total number of sheep distributed = 10 + 5 + 4
= 19 sheep
The remaining one sheep is returned. So, no sheep has remained.

Question 2:
Write the next three numbers in the series
(i) 10, 20, 30, _, _, _
(ii) 10, 9, 8, _, _, _
(iii) 1, 3, 5, 7, 9, _, _, _
Solution:
(i) The given series is 10, 20, 30, _, _, _
The series is multiple of 10 and the list is natural numbers.
1 x 10 = 10
2 x 10 = 20
3 x 10 = 30
So, 4 x 10 = 40
5 x 10 = 50
6 x 10 = 6
The next three numbers in the series are 40, 50, 60
(ii) The given series is 10, 9, 8, _, _, _
The series in the reverse order of natural numbers starting from 10
10 – 9 = 1
9 – 8 = 1
8 – 7 = 1
7 – 6 = 1
6 – 5 = 1
Therefore, the next three numbers in the series are 7, 6, 5.
(iii) The given series is 1, 3, 5, 7, 9, _, _, _
The numbers in the series are prime numbers.
Prime numbers are the numbers that are divisible by 1 and the number itself.
The next 3 prime numbers are 11, 13, 17

Question 3:
Write a 3 x 3 magic square that has numbers from 1 to 9 and sum of rows or columns or diagonals is 15.
Solution:
Given that,
The list of numbers in the 3 x 3 square should be 1, 2, 3, 4, 5, 6, 7, 8, 9
The sum of numbers in every row = 15
The sum of numbers in every column = 15
The sum of numbers in every diagonal = 15
The possibility of the arrangement of numbers is given below. Check the condition:
The sum of numbers in 1st row = 1 + 5 + 9 = 15
The sum of numbers in 2nd row = 6 + 7 + 2 = 15
The sum of numbers in 3rd row = 8 + 3 + 4 = 15
The sum of numbers in 1st column = 1 + 6 + 8 = 15
The sum of numbers in 2nd column = 5 + 7 + 3 = 15
The sum of numbers in 3rd column = 9 + 2 + 4 = 15
The sum of numbers in one diagonal = 1 + 7 + 4 = 15
The sum of numbers in second diagonal = 9 + 7 + 8 = 15
