On planet Simplon, each year has 12 months, each of which consists of exactly 30 days. If Simplon experiences a political scandal every 2/3 of a year, an environmental crisis every 1/6 of a year, and a terrible movie opening every 1/36 of a year, then what is the ratio of the number of political scandals to the number of environmental crises to the number of terrible movie openings experienced over a five year period on Simplon? (Assume that all three events happen 2/3, 1/6, and 1/36 of a year after the beginning of the first year, and recur at their respective rates after that.)
A. 24 : 4 : 1
B. 1 : 4 : 24
C. 4 : 15 : 90
D. 1 : 6 : 36
E. 3 : 10 : 72
Total days per year = 12*30=360
For 5 years = 12*30*5=1800
political scandal happens every 2/3 of a year = 2/3 * 360 = 240days
This implies for every 240 days 1 political scandal occurs.
which means for 5yrs or 1800 days, no.of scandals that happen = 1800/240 =
15/2smilarly environment damage happens every 1/6 of a year = 1/6 * 360 = 60 days
This implies for every 60 days 1 environmental damage occurs.
For 5yrs or 1800 days, no.of environmental damages that occur = 1800/60 =
30smilarly a terrible movie opening happens every 1/36 of a year = 1/36 * 360 = 10 days
This implies for every 10 days 1 terrible movie opening happens.
For 5yrs or 1800 days, no.of environmental damages that occur = 1800/10 =
180Answer==> political scandal for 5yrs : Env damages for 5yrs : Terrible movie opening for 5yrs = 1800/240 : 1800/60 : 1800/10
or 15/2 : 30 : 180 = 15 : 60 :360 = 1 : 4 : 24
