Better to make this payment with rupees (5)
I believe the answer is:
wager
'better to make this' is the definition.
(someone who bets might make a wager)
'payment with rupees' is the wordplay.
'payment' becomes 'wage' (wage is a kind of payment).
'with' says to put letters next to each other.
'rupees' becomes 'r' (abbreviation for rupees).
'wage'+'r'='WAGER'
(Other definitions for wager that I've seen before include "Put on a bit" , "better to put this on?" , "Risk; stake" , "act for "The Gamblers"?" , "(Place a) stake" .)
