Answer 1

If he makes a deposit of of $830 dollars in a currency 3x the dollar, the amount, $830 will be equivalent to:

`(830)/(3)\cong276.67\text{ units of the unknown currency}`

In that case, he deposited 276.67 units of the unknown currency in cheque

and 276 units in currency since coins are not an option.
