225 == 175 - If the number of hotels in 2006 in place C was 150% of the number of hotels in place C in 2005, then what was the ratio of the number of hotels in places A and B combined to the number of hotels in place C and D combined in 2006?
20:3327:3831:3511:2221:32Option E

Number of hotels in 2006 in place C = 1.5*40 = 60

Total number of hotels in A and B combined in 2006 = 80+25 = 105

Total number of hotels in C and D combined in 2006 = 60+100 = 160

Required ratio = 105:160 = 21:32 - If the number of hotels in palce A in 2007 is equal to the average of the number of hotels in place B in 2008 and in place C in 2007, then the total number of hotels in palce D in 2006 and 2007 combined was approximately what percentage of he total number of hotels in place A during the 4 years combined?
79.55%80.03%70.78%72.73%62.66%Option D

Number of hotels in place A in 2007

= (80+100)/2 = 90

Total number of hotels in place D in 2006 and 2007 combined = 100+140 = 240

Total number of hotels in place A during 4 years combined = 50+80+90+110 = 330

Required% = 240/330*100 = 72.73% - The total number of hotels in place C during the 4 years combined was 330. What was the ratio of the total number of hotels in place C in 2005 and 2007 combined to the total number of hotels in place C in 2006 and 2008 combined ?
19:2013:2114:1915:1717:20Option C

Total number of hotels in place C in 2005 and 2007 combined = 40+100 = 140

Total number of hotels in place in 2006 and 2008 combined = 330 – 140 = 190

Required ratio = 140:190 =14:19 - If the total number of hotels in 2008 in the 4 places combined was 250 more than the number of hotels in place D in 2007 , then what was the number of hotels in place D in 2008?
881009012095Option D

Total number of hotels in 2008 in the 4 places combined

= 140+250 = 390

Let the number of hotels in C and D in 2008 be 2x and 3x.

Then, 110 + 80 + 2x + 3x = 390

=> x = 40

Hence, Number of hotels in place D in 2008

= 3x = 120 - What was the total number of hotels in place B in 2005 ?
