Answer 1

Hint: In this problem we apply a unitary method. In this we first calculate the fee for one month and then multiplying it with seven to calculate the fee for seven months.

Complete step-by-step answer:
Quarterly school fee in Kendriya Vidyalaya for class VI is$540$.
Here, quarterly means a fee for $4$months.
We use a unitary method to find a fee for seven months.
Therefore, we calculate fee for one month first:
Fee for $4$ months is = $540$
$\Rightarrow$ Fee for one month $={\displaystyle \frac{540}{4}}$
Fee for one month $=135$
Now, we use one month fee to calculate the fee for seven month by multiplying it by seven.
Fee for seven months =$135\times 7$
$\Rightarrow$ Fee for seven months = $945$
Therefore, from above we see that school fee in Kendriya Vidyalaya for seven months is.$945$.

Note: While, using unitary method we must see what are the given conditions given in problems and then first calculate for one unit and then using it to find value for required number of units asked in given problem.
