In school there are some bicycles and 4wheeler wagons.one Tuesday there are 190 wheels in the campus. How many bicycles are there?

• Answer is calculate using the options given in the answer..
  for example total wheels are 182 and options are a.20 b.19 c.18 d.16
  so we can possibility using the given values.
  a.---> 20*2=40--->182-40--->142--> for 4 wagons 142/4 is not possible so a is not true.
  b.--->19*2=38--->182-38--->144--> for 4 wagons 144/4=36 is possible so b is true.
  c.---->18*2=36--->182-36--->146--> for 4 wagons 146/4 is not possible so c is not true.
  d.---->16*2=32--->182-32--->150--> for 4 wagons 150/4 is not possible so d is not true.

• Ans is :19
  @MARIA SHANA
  OPTIONS ARE 20,19,18,16
  190 wheels in the campus
  some bicycles and 4wheeler wagons
  20 bicycles =20*2=40=190-40=150/4 is not possible
  19 bicycles=19*2=38=190-38=152/4 is possible
  18 bicycles=18*2=36=190-36=154/4 is not possible
  16 bicycles=16*2=32=190-32=158/4 is not possible

• cannot determine without knowing how many bicyles are there

• 2x+4y=190
  y=(190-2x)/4
  only satisfying odd value of x , 1,2,3...

• @CHINTAN MAKWANA- can u pls xplain y we are taking the total wheels to be 182 when its 190???

• lets b be no of bicycles and w be no ot wagons....
  2b+4w=190
  we have 2b=1w so..
  2b+4*2b=190
  10b=190
  b=19
  so no of bicycles are 19.

• answer option is = a 20 b 15 c 16 c17
  now the ans is" b"
  bcz whwn you divide 190 it mens is also divided by 2 and 4 but it is not there so take opt. b = 15*2 = 30 now 190-30 = 160 and 160 is divisible by 4
  now i think you all understand the logic go with the logic ok all the best akash.chouhan99@gmail.com

• Let us assume no. of bicycles to be x and wagons to be y.
  Then, 2x + 4y = 190
  also, x:y=2:4 (no. of wheels is directly proportional to number of bicycles)
  then 2x=y.
  
  solving these two, we get y=38 and x=19.
  
  We can check the solutions as well. 19x2 + 38x4 =190 which is indeed true.

• Let there are B bicycles and W wagons.
  
  
  
  Total number of wheels = 2 × B 4 × W
  
  
  
  Given 58 wheels ⇒ 2B 4W = 58
  
  
  
  ⇒ B 2W = 29 …… (Eq.1)
  
  
  
  Also given B W = 18 …… (Eq.2)
  
  
  
  ∴ Eq.1 – Eq.2
  
  
  
  ⇒ W = 11
  
  
  
  ⇒ B = 18 – W
  
  
  
  ⇒ B = 18 – 11 = 7 Bicycles.
