One India Rupee value was 13$ in 1917 (But now why it is lesser)

Once there was a time Indian Rupee have more value.

  In 1917 , Rs 1= 13$ USD.

But now there is lowest value of Indian rupees.

In 2015, 1$ USD = Rs 63.

What's the reason?
Why Indian rupee got less value?
Why India is not a fully developed country till now?
