So a major part of the problem I have on the SHL numerical is that I simply get confused when something is written like

Last year, the value of the High Yield Equities holding was 10% less than what it is now. What was the value of the High Yield Equities holding last year?

Or

If the number of cars that are greater than 6 years old has grown by 30% between 1994 and 2001, how many cars were less than 6 years old in 1994.

Can someone let me know how I can tell when the wording wants me to multiply the original number by 1.3?

Another example is “If the euro fell in value by 11%, how many euros could you buy for 1500 Ringit?”

Why is it in this case this sentence still means take the original value of the euro and multiply it by .89 instead of take the original value and divide it by 1.11?
