Unitary Method is that in which for further calculation value of unit (1) is required for further calculation.

Unit means one, mathematically ‘1’.A, An or Per also mean ‘1’.*If we know the value of one then to find value of many we do MULTIPLICATION. Read this problem and the table.*

Problem 1: Cost of one mango is $ 4. Find the cost of 8 mangoes.–

One | Many |

1 | 8 |

$ 4 | ? |

Solution:

As the Cost of 1 mango is $ 4.

Therefor the cost of 8 mangoes is 8×4 = $ 32

Also Watch solution in the video given at the bottom .*If we know the value of many then to find value of one we do DIVISION. Read this problem.*

Problem 2: Cost of one mango is $ 4. Find the cost of 8 mangoes.–

Many | One |

8 | 1 |

$ 40 | ? |

Solution:

As the Cost of 8 mango is $ 40.

Therefor the cost of 1 mango is 40/8 = $ 5

Also Watch solution in the video given at the bottom .*If we know the value of many then to find value of many we first need to calculate the value of 1. **Note: students of lower classes faces more difficulties in this type of sum of unitary method. But it is very easy. The s only need to know the atone two methods. Because this sum is the combination of the above two methods.** Read this problem.*

Problem 2: Cost of 8 mangos is $ 40. Find the cost of 4 mangoes.–

Watch solution in the video.given at the bottom .

Many | Many |

8 | 4 |

$ 40 | ? |

Solution:

As the Cost of 8 mango is $ 40.

Therefor the cost of 1 mango is 40/8 = $ 5

Therefor the cost of 4 mango is 4×5 = $ 20
