Answer 2

Answer:

The cost of 9 toy is Rs. 40.5

Step-by-step explanation:

Given information,

the cost of 20 toy is Rs. 90

We have to find out the cost of 9 toy

As,

The cost of 20 toy = Rs. 90

The cost of 1 toy = $\frac{the \: cost \: of \: 20\: toy }{20}$

The cost of 1 toy

$= \frac{90}{20}$

By dividing 90 by 20 we get

The cost of 1 toy $= 4.5$

The cost of 9 toy = The cost of 1 toy × 9

The cost of 9 toy = $4.5 \times 9$

The cost of 9 toy = $40.5$

Hence,

The cost of 9 toy is Rs. 40.5
