Correct Answer: NIL
Solution:
The total amount he wants to deposit =300000
let the amount deposit in bank =x
and in post office = Rs (300000-x)
he earned 2000 rupees monthly interest, for 1 year he he earned 12*2000=24000
By using simple interest formula
10% in post office+6% in bank =24000
\(\frac{10*(300000-x)*1}{100}+\frac{6*x*1}{100} = 24000\)
By solving the above equation we get x=150000
so, he invested 150000 in bank and 150000 in post office. hence the difference is NIL
