### Question

If ${13/20}$ of a number is 23, what is $1{10/13}$ of that number?

**A**

$62{102/169}$.

**B**

$63{55/56}$.

**C**

$60{151/171}$.

**D**

$64{143/171}$.

**Soln.**

**Ans: a**

Let the number be N. Then it is given that ${13/20}$ x N = 23. ⇒ N = 23 X ${20/13}$. ⇒ ${23/13}$ x N = ${23/13}$ x 23 X ${20/13}$ = ${10580/169}$.

*${23/13}$ is same as $1{10/13}$. ${10580/169}$ is same as $62{102/169}$. *
