2x+3x=10

5x=10

x=2

3x= 3×2=6

Answer 2

Concept:

To determine the value of a single unit from a specified multiple, use the unitary method . How to determine the value of one pen, for instance, if the cost of 40 pens is Rs. 400. The unitary method can be used to complete it. Additionally, after determining the value of a single unit, we can multiply that value by the number of units needed to determine the value of the additional units. The concept of ratio and proportion is mostly applied using this way.

Given:

A sum of rs. 10 consists of one rupee coins and 50 paise coins in the ratio 2:3.

Find:

What is the total no. of 50 paise coin

Solution:

let ratio be x

therefore 2x,3x

1 ruppee amount=1 . 2x=2x

50 paise amount==0.5 x 3x =1.5x

As per question.

2x+1.5x=10

3.5x=10

x=2.875

So total no. of 50 paise coins =2.875 x 3

                                                 =8.625≈8 coins

Therefore, the no. of 50 paise coins =8
