If we have $7,874,016 and we want the equivalent in pounds, then it means we are selling the first currency which is ($). The appropriate rate to use should then be the higher rate which is £1.6283. This is the understanding from previous studies.

However, you divided the $7,874,016 with the lower rate which is £1.6201.

Hello Sir, in example 6 while borrowing, we divided the 5M with 1+the interest rate. but in example 7 the amount borrowed is multiplied with 1+the interest. may you please explain why we cant divide the amount to be borrowed with the interest in example 7. thanks

I do actually explain in the lecture that interest rates are always quoted as annual rates even though they only apply to loans and deposits for the period stated (in this case 3 months). If the loan or deposit was for 6 months then the interest rate quoted would still be quoted as an annual rate, but would be a different annual rate.

Hi Sir, When you convert the $ deposit of 7,874,016 to find out how many pounds you need to borrow, shouldn’t you divide by 1.6283 because you will have to sell $’s to buy pounds?

Thank you sir.

In this example we are buying dollars (not selling them), so that we will have enough to later (when interest is added) to be able to pay the $8M.

If you borrow money, then at the end of the period you are owing more money.

The question says 3 months interest rate why have you converted it yet again to a monthly rate

Hello, i am really confused about when to divide and when to multiply. Can someone help me please. Thank you

John Moffat says

Have you watched the first in this series of lectures?

zaidrafiqkhan says

Basically this is the core problem most students faced,

Just remember one simple thing you have to pay high and receive low amount… so do your calculations in that way.

noormkhan says

Use the following table

First currency. Second currency

Payments _We buy Low rate High rate

We sell. High. Low

Conversion Division Multiplication

douglasnyangara says

Use cross multiplication, if $1.6= 1 pound , then $8M = ?

John Moffat says

If you want to deposit $’s then you need to buy $’s in order to have $’s to put on deposit.

rehan1o1 says

same question sir, kindly reply

John Moffat says

I did reply the same day – the reply is above the question 🙂

douglasnyangara says

Always work on the assumption that you’re at a disadvantage, you need to borrow, what rate makes you borrow the most?

mariyaaa says

Thanks. Finally you said it the easy way! I had been so confused.
