The worked question on this page is original educational practice. It is not represented as a question from an official previous-year examination paper.
01 / UNDERSTANDING
Review the question
Prepare original questions that reverse the required output currency while keeping the quote unchanged. Require unit cancellation beside the answer to reveal guessing that may otherwise appear correct.
02 / UNDERSTANDING
The concept in context
A two-way quote distinguishes the dealer’s buying and selling sides. The customer’s action is the opposite side of the dealer’s action, so perspective matters. Real rates, fees and rounding vary and must be obtained from the actual provider; an educational quote exists only to practise units and direction, not to state a current market price.

A worked learning case
Original educational case. Using a purely hypothetical quote of ₹80 per dollar and ignoring fees, 250 dollars convert to ₹20,000. Conversely, ₹12,000 convert to 150 dollars at that same one-way quote. A learner writes dollars × rupees per dollar for the first calculation, allowing the dollar units to cancel and leaving rupees as the result.
ORIGINAL EDUCATIONAL PRACTICE
Try it before you check.
Original practice: At a hypothetical rate of ₹75 per dollar, how many dollars equal ₹15,000, ignoring fees?
Show the answer and reasoning
200 dollars.
The quote gives rupees for one dollar, so divide rupees by rupees per dollar: 15,000 ÷ 75 = 200. Multiplying would produce the wrong unit direction. This is a stated practice conversion only; it does not represent a live rate or imply that actual buying and selling quotes are identical.
Two traps to watch for.
- Multiplying rupees by a rupees-per-dollar quote to obtain dollars.
- Reading the customer’s purchase as the dealer’s purchase.
