Answer 2

Answer:

The cost of 4 toy is Rs. 140 .

Step by step Explanation :

Given information,

the cost of 3 toys is Rs. 75

We have to find out the cost of 4 toys

As,

The cost of 3 toys = Rs. 75

The cost of 1 toy = $\frac{the \: cost \: of \: 3\: toys }{3}$

The cost of 1 toy

$= \frac{75}{3}$

By dividing 75 by 3 we get

The cost of 1 toy $= 35$

The cost of 4 toy = The cost of 1 toy × 4.

The cost of 4 toy = $35 \times 4$

The cost of 4 toy = $140$

Hence,

The cost of 4 toy is Rs. 140 .
