Entry fee is Re.1.there are 3 rides each is of Re.1. total boys entering are 3000.total income is Rs.7200. 800 students do all 3 rides. 1400 go for atleast 2 rides.none go the same ride twice. then no of students who do not go any ride is?
Pick one:
A) 1328
B) 1000
C) 2378
D) 8287
E) 1872
Total entries are 3000 So fee collected through entry fee = 3000 x 1 = Rs.3000   Income generated through rides = 7200 - 3000= 
<gadget id="calculator">7200 - 3000</gadget>
<output>4_200</output>
4200   Now 800 went for 3 rides so total fee paid by these 800= 800 x 3 = 2400   (1400 - 800) went for 2 rides so fee paid by these 600 = 600 x 2 = 1200   Assume K went for exactly 1 ride   Then K x 1 + 1200 + 2400 = 4200 ⇒⇒ K = 600   So number of boys who did not go for any ride = 3000 - (600 + 600 + 800 )= 
<gadget id="calculator">3000 - (600 + 600 + 800 )</gadget>
<output>1_000</output>
1000   Answer:1000
<result>B</result>
