  1. Rs. $2725$

  2. Rs. $3500$

  3. Rs. $1500$

  4. Rs. $2800$

Show answer
Correct Option: B
Explanation:

Let $100$ Rs note be $x$ and $50$ Rs note be $y$

Total number of notes =$x+y=85$................(1)
Total amount of these currency notes + $5000=100x+50y$.............(2)
Multiplying equation 1 with $50$
therefore we get $50x+50y=4250$.......(3)
Subtracting equation 3 from equation 2, we get
$50x=750$
$x=15$
Substituting $x=15$ in equation 1, weget $y=70$
Amount in dominnation of $50$ Rs=$70\times 50=3500$
