Question

If the cost of $25$ tables is $Rs31625$, then:

_____ such tables can be bought for $Rs10120$

Answer 1

Given that,

Cost of $25$ tables $=$ $Rs31625$

Assume , cost of $x$ tables $=$ $Rs10120$

In proportion, it can be written as:

$25tables:x::Rs31625:Rs10120$

Therefore,

$$\begin{gathered} \frac{25tables}{x}=\frac{Rs31625}{Rs10120} \\ x=\frac{25\times 10120}{31625}tables \\ x=8tables \end{gathered}$$

Hence, $8$ such tables can be bought for $Rs10120$
