Answer 2

Answer:

The amount left with Radha by a end of 30th January is Rs.315

Step-by-step explanation:

Starting from 1st January Radha decided to save the amount equal to the date of the month

On 1 January , she will save Re.1

On  2 January , she will save Rs.2  and so on

So, Sum of amount on 30th Jan = 1+2+3+........+30

Formula of sum of first n natural numbers = $\frac{n(n+1)}{2}$

Substitute n = 30

So,  Sum of amount on 30th Jan = $\frac{30(30+1)}{2}=465$

So, she should save rs.465 till 30th Jan

On 30th January, she distributed bananas for Rs.50 and apples for Rs. 100.

So,  the amount left with Radha by a end of 30th January = 465-(50+100) =Rs.315

Hence the amount left with Radha by a end of 30th January is Rs.315
