In funny math answers we will learn how to solve answers in tricky method. Students will gain subject knowledge and can also spend their time in practicing the quicker method joyfully. In the funny math, students can also learn how to use the different tricks in different types of math problems. Let us follow some of the tricky and quicker method problems in the following below:



For Example:

1. A man spends ¹/₅ of his salary on food, ¹/₁₀ of his salary on house rent and ³/₅ of his salary on clothes. He still has $18000 left with him. Find his salary.

Solution:

The expenditure incurred on each item is expressed as part of the total amount (salary), so it is an independent activity.

In general for independent activities

[1 – (^x₁/_y1 + ^x₂/_y2 + ^x₃/_y3)] × Total amount = Balance amount

[1 – (¹/₅ + ¹/₁₀ + ³/₅)] × Total salary = $18000

[1 – ⁹/₁₀] × Total salary = $18000

Therefore total salary = $18000 × 10 = $180000



2. A number when divided by 899 gives a remainder 63. What remainder will be obtained by dividing the same number by 29.

Solution:

63 ÷ 29

Therefore required answer = 5.



3. The sum of two numbers is 75 and their difference is 20. Find the difference of their squares.

Solution:

If the sum of two numbers is x and their difference is y, then the difference of their squares is xy.

Here x= 75 and y = 20

75 × 20 = 1500



4. The difference between the squares of two consecutive numbers is 37. Find the numbers.

Solution:

If the difference between the squares of two consecutive numbers is x, then the numbers are ^(x-1)/₂ and ^(x+1)/₂

^(37-1)/₂ and ⁽³⁷⁺¹⁾/₂

³⁶/₂ and ³⁸/₂

Therefore the required answer = 18 and 19.



5. Two consecutive numbers are 8 and 9. Find the difference of their squares.

Solution:

If the two consecutive numbers are x and y, then the difference of their squares is given by x + y.

Here, x = 8 and y = 9.

8 + 9

Therefore the required answer = 17
