Bhatia, Ashtikar and Singh begin to play with Rs 70 each. At the end the ratio of the amounts left
with Ashtikar and Singh is 1 : 2 and of those with Singh and Bhatia is 4 : 1. What is Singh's gain
(in Rs)?

• Singh's Gain is Rs.50
  
  sol. We have b+a+s = 210
  and s = 2a, s = 4b and a = 2b
  
  solving these EQs we got
  that singh have Rs.120 in the end
  Bhatia have 30
  and Astikar have 60.
  so singh's profit is 120 - 70 = 50 (70 was his Buy in)
  
  Verify
  120+30+60 = 210

• At the end , ratio of amounts of Ashtikar, Singh and Bhatia are 2:4:1.
  so out of total Rs 210 (3*70), share of Singh is 210*4/7 = Rs 120.
  
  so Singh's gain = Rs 120-70 = Rs 50.

• a:s=1:2
  s:b=4:1
  hence the a:s:b will be 2:4:1
  so for singh =210(4/7)=50

• ANS: 120RS
  total 70+70+70 = 210
  a:s=1:2 ; s:b=4:1 lcm of 2,4 = 4 (to equate the ratios)
  a:s = 2:4 s:b =4:1 now a:s:b = 2:4:1
  2x+4x+x = 210 ; 7x=210 ;x = 30 end they got S=4x=4*30=120RS ;B=2x =2*30=60RS A=30

• 1:2 and 4:1
  1*2:2*2::4:1
  2:4:1
  (4/(2+4+1))*210=120
  120-70=50
