Answer 1

It is given that the ratio of income to saving is 7:3

The monthly income is given to be rupees 27300

Let the monthly income be 7x and the saving be 3x

So, as per the given condition

7x = 27300

x= 3900

Now putting the value of x in the savings.

3x = 3 × 3900

     = 11,700

The monthly savings will be rupees 11,700

Answer 2

It is given that the ratio of income to saving is $7: 3$

As per data given in the question,

We have to determine the value of monthly saving.

As per data,

The monthly income = Rs. 27300

As the ratio of monthly income and monthly saving is 7:3

So,

Let the monthly income be 7x and the saving be 3x.

So,  

$7 x=27300 \\x=\frac{27300}{7} = 3900$  

Now putting the value of x for finding his savings.

We will get,  

$3 x &=3 \times 3900 =Rs\:11,700$  

Hence, the monthly savings will be rupees Rs. 11,700.
