We know FF(flash floods) and Tornadoes in Aug'14 are approx. 30 and 10 respectively.

Now we are given that '14 FF and Tornadoes are 25% more than '13 so essentially we are saying 125/100*FF('13)=30 and 125/100*Tornadoes('13)=10.

Hence we get 24 and 8 respectively.

Now for '15 we are told FF increased by 1/3 so that is 30+1/3*30=40 and Tornadoes increased by 1/2, which is 10+1/2*10=15.

Therefore our difference of events is 55–32=23.


how would you tell that FF(flash floods) and Tornadoes in Aug'14 are approx. 30 and 10 respectively?
can you explain?

Just look at the first line graph. At the FF total and Tornado's total lines respectively.
