• equating it , would become..300x+200y+5Z=10000...and answer can be found by substituting the options..!!

• let the number of shares of indigo , hul and sbi be x,y and z respectively.
  according to the condition total number of shares are 100 i.e x+y+z=100 and total amount is 10000 i.e
  it is equal to the sum of the amounts of x shares of indigo(300 rs) , y shares of hul(200 rs) and z shares of sbi (5 rs) i.e 300x+200y+5z=10000 ........on so;ving the above two equations ,we finally get 295x+195y=9500 (z term is to be cancelled by solving since we only need x(indigo) and y(hul)). by substituting options in the final equation we can check the answers ....i.e x=17 and y= 23

• take values by using options one by one
  15*300+25*200+60*5=9800 so wrong answer
  we got a view that 2 nd option is not suitable so take 3 rd option
  15*300+23*200+60*5=10000
  
  why we got 60 means total 100 so 15+23=40 so remaining 60 so thats the reason we took 60 for sbi.

• 17*300+23*200=9700 .this option is near to 10000.

• 300*a +200*b+5*c=10000 c= 100-(17+23)= 60
  300*(17)+ 200 *(23)+5*(60) = 10000

• Options are -
  
  (1) 15, 25
  
  (2) 23, 17
  
  (3) 17, 23
  
  (4) 17, 60
  
  ◆ Answer -
  
  (3) 17, 23
  
  ◆ Explanation -
  
  Let x, y and z be no of shares Raj bought in Indigo, Hul and SBI respectively.
  
  Given that total no of shares are 100.
  
  x + y + z = 100 ...(1)
  
  300x + 200y + 5z = 10000 ...(2)
  
  So here,
  
  300x + 200y + 5z = 10000
  
  60x + 40y + z = 2000
  
  60x + 40y + 100 - x - y = 2000
  
  59x + 39y = 1900
  
  This eqn can be satisfied by multiple solution.
  
  From the options, x = 17 & y = 23 satisfy eqn,
  
  LHS = 59×17 + 39×23
  
  LHS = 1900
  
  LHS = RHS
  
  Hence, answer is 17 and 23.
