find the no of ways a batsman can score a double century only in terms of 4's and 6's?
a)15
b)16
c)17
d)19

• sorry....for the 1st answer
  CORRECT ANSWER IS 16
  LCM OF 6 & 4 =12
  200/12=16.66=16(APPROX)(FLOOR VALUE)

• 4's and 6's
  ------------
  50 0
  47 2
  44 4
  41 6
  38 8
  35 10
  32 12
  29 14
  26 16
  23 18
  20 20
  17 22
  14 24
  11 26
  8 28
  5 30
  2 32
  So total 17 ways but here it is 4's & 6's both so don't consider 1st one
  Final ans : 16 ways

• Ans:16
  4s and 6s
  =3:2
  Starting position 4's and 6's
  50 0
  reduce 3 in 50 every iteration up to coming 2...
  increase 2 in 0 every iteration up to coming 32...
  there are 17 no of ways...
  50 0 is not possible..
  17-1=16

• 1. 4*50 + 6*0 =200
  2. 4*47 + 6*2 =200
  3. 4*44 + 6*4 =200
  4. 4*41 + 6*6 =200
  .
  .
  .17. 4*2 + 6*32 =200
  here we see that multiple of 4 is decreasing constantly by 3
  n makes an A.P. where a=50, d=-3 & an=2
  by formula, a+(n-1)d=an
  50+(n-1)(-3)=2
  n=17
  so, no. of ways = 17

• let 100 no batsman
  L.C.M of 4 and 6 is 12
  200/12=16.6
  16 ways

• 16 ways he can hit 200
• 10 years agoHelpfull: Yes(2) No(3)
• 4x+6y=200;
  2x+3y=100;
  x=(100-3y)/2;
  x=50-3y/2;
  take integer value of x and y
  then by solving this equation we get first value y=2 and x=47,y=4,x=44 and in this way difference b/w two consecutive no in term of x=3...now we put progression formula to find no of term.tn=a+(n-1)d
  47=1+(n-1)3
  then n=15.33
  i.e.n=16

• LCM of 6 and 4 is 12.
  i.e., for every difference of 12 runs combination of 4's and 6's are possible
  Therefore, possible ways is 200/12=16.67
  i.e., 16 no. of ways
• 10 years agoHelpfull: Yes(2) No(0)
• 16 ways he can hit
  
• 10 years agoHelpfull: Yes(1) No(3)
• LCM of 6 &4 is 12
  200/12=16.66=17(approx)
  so ans is 17
• 10 years agoHelpfull: Yes(1) No(1)
• Answer is 16,They asked 4's and 6's----so, 50*4,0*6 is not valid.
  Totally 17 possibility.
  So,17-1=16

• @karthikeyank
  i think 2 six makes 3 fours
  so 2n*6+3m*4=200
  =>n+m=200/12=16.6 smthng
  so 16 is the ans.

• 16*6+1*4=200 so 17

• 16 as the combinations are 12,24,....192.so the no of cmbinations are 16
• 10 years agoHelpfull: Yes(0) No(0)
• can anyone tell the answer whether it is 16 or 17
  
• 10 years agoHelpfull: Yes(0) No(0)
• 16 is correct ans
• 10 years agoHelpfull: Yes(0) No(0)
• 16 ways.
  As lcm of 6 and 4 is 12
  200/12 = 16.66(floor value)
