**A**

$22{356/483}$.

**B**

$23{379/482}$.

**C**

$21{314/485}$.

**D**

$25{306/485}$.

**Soln.**

**Ans: a**

Let the number be N. Then it is given that ${23/34}$ x N = 17. ⇒ N = 17 X ${34/23}$. ⇒ ${19/21}$ x N = ${19/21}$ x 17 X ${34/23}$ = ${10982/483}$.

*${10982/483}$ is same as $22{356/483}$. *
