Answer :
Given : A man's monthly income is Rs.34475. He opens a savings account with an initial deposit amount of Rs. 5000 on 1st January 2010.
So,
Balance on his account on 2nd January 2010 = 34475 - 5000 = Rs . 29475
Salary is credited on 3rd of every month. , So
Balance on his account on 3rd January 2010 = 29475 + 34475 = Rs . 63950
And
Rs. 15000 would be deducted from his salary account on the 20th of every month.First investment was done on 20th February 2010.
Balance on his account on 3rd February 2010 = 63950 + 34475 = Rs . 98425
And
Balance on his account on 20th February 2010 = 98425 - 15000 = Rs . 83425 ,
Balance on his account on 3rd March 2010 = 83425 + 34475 = Rs . 117900
And
Balance on his account on 20th March 2010 = 117900 - 15000 = Rs . 102900 ,
Balance on his account on 3rd April 2010 = 102900 + 34475 = Rs . 137375
And
Balance on his account on 20th April 2010 = 137375 - 15000 = Rs . 122375
And
Balance on his account on 3rd May 2010 = 122375 + 34475 = Rs . 156850
And
Balance on his account on 20th May 2010 = 156850 - 15000 = Rs . 141850
Therefore ,
Balance on his account on 25th May 2010 = Rs . 141850 ( Ans )
