- 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 - 8 years agoHelpfull: Yes(7) No(0)
- 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. - 3 years agoHelpfull: Yes(0) No(0)
