If the cost of 7 m of cloth is Rs. 1470, find the cost of 5 m of cloth.
Given:
The cost of $7\ m$ of cloth is $Rs.\ 1470$.
To do:
We have to find the cost of $5\ m$ of cloth.
Solution:
The cost of $7\ m$ of cloth $= Rs.\ 1470$
This implies,
The cost of $1\ m$ of cloth $=\frac{1470}{7}$
$= Rs.\ 210$
Therefore,
The cost of $5\ m$ cloth $=5\times210$
$= Rs.\ 1050$
