Manish buys a ₹8.75 metro ticket with a ₹20 note. How much money does he get back?

Given:

Total money = ₹20.00

Cost of ticket = ₹8.75

Money received back = ?

∴ Money received back = (Total money) - (Cost of ticket)

Substituting the values in above, we get:

Money received back = ₹20.00 - ₹8.75

Converting the given decimals into like decimals, we have to subtract 8.75 from 20.00.

Subtracting columnwise, we get:

$\begin{array}{r} 20.00 \ -\phantom{0}8.75 \ \hline 11.25 \ \hline \end{array}$

Hence, he gets back ₹11.25
