### CFA Practice Question

Suppose the Brazilian real is quoted at \$:R = 0.9955 - 1.0076 and the Thai baht is quoted at \$:B = 25.2513 - 3986. What is the direct quote for the real in Bangkok (R:B)?

A. 30.5541 - 6456
B. 25.1376 - 2654
C. 25.0608 - 5134

Bid cross rate for the real (R:B) = 25.2513/1.0076 = 25.0608
Ask cross rate for the real = 25.3986/0.9955 = 25.5134
Therefore, the direct quotes for the real in Bangkok (R:B) are 25.0608 - 5134.

schweitzdm I can't be the only one loathing this section
robbiecow Best way to think about this is if you get it the question in Bid-Ask format and are asked for the cross rate just think of the letter "X" for cross and align each Bid-Ask to the correct point.
ankurwa10 Please explain the entire approach Robbiecow, including how you solved it. Thanks
ankurwa10 On second thoughts, here's how I got the answer right. Don't know if the approach is right.

the concept of cross-currency is that: you sell one currency (GBP) to get some \$; and then use this \$ to buy another currency (Bhat)

now, when selling GBP --> you need the highest price, so use the ask rate.

i.e. since \$:R => R/\$ = 1.0076 (remember the reading where it says that if S => a:b (in division terms it is b/a)

when buying Bhat --> you need the cheapest price, so use the bid rate.

i.e. since \$:B => B/\$ = 25.2513

Now, solve to eliminate the \$, you get R/B = 25.2513 and since R/B => B:R which is the Direct quote for Bhat:GBP.

What I am confused about is why do separate bid/ask rate calculations. Also, does the concept I outlined above apply to this method (that of calculating bid and ask spread)
oprea_cl QUICK TIP: If the BASE currency is on:
1. Same side - cross divide the quotes (larger nr / smaller number)
2. Different sides - multiply same side
Price/Base bid - sell base

THB/BRL bid - value of THB received when selling 1 BRL (sell base)

you only need to calculate 1 to eliminate the other answers. I chose to find the bid by seeing how much THB i get for selling 1 BRL

Sell 1 BRL & Buy 'x' USD - use ask price of BRL/USD because you're buying base:

[invert the ask price to end in USD and not BRL^2/USD]
x = 0.992457 USD/BRL * 1 BRL
x = 0.992457 USD

Sell USD & Buy 'y' THB - use bid price of THB/USD because now you're selling base:

bid = 25.2513 THB/USD
[don't invert because otherwise you'll end up with USD^2/THB]
y = 25.2513 THB/USD * 0.992457 USD
y = 25.0608 THB
ashish100 Find value 1 unit of currency used on both sides.

Use two values and equal them together
