How to find a minor currency prices by using 7 major currencies?

[Asad Raza]

I need a formula to do some programming.

There are 7  major currency

EUR/USD, USD/JPY, GBP/USD, USD/CHF, AUD/USD, USD/CAD, NZD/USD

Now what is the formula to find other minor currency prices by using major currency prices?

.

I found on internet these formulas

EURUSD TO USDEUR

Formula: 1/EURUSD = USD/EUR

EURUSD,EURJPY TO USDJPY

Formula: EURUSD/EURJPY = USDJPY

But how to find ZAR/USD or INR/USD, OR JPY/ZAR price by using only 7 major currency?

i read 7 are major currency, these currencies control all minor prices movement.

USD and EUR have no values so the formula is nonsense.

They only have values when compared to another currency.

But how to find ZAR/USD or INR/USD, OR JPY/ZAR price by using only 7 major currency?

Not possible.
