A and b invested Rs.6000 and Rs.x respectively. They get a profit of Rs.5000 at the end of year in which share of b is 2000. what is the value of x?

a)
Rs.4000
b)
Rs.3000
c)
Rs.2000
d)
Rs.2500


2)In what proportion should two quantities of gold one of 16 carats and another of 20 carats be mixed so that mixture in the form of jewellery may be 17 carats pure?

3:1
1:3
2:3
3:2

• A=Rs 6000
  B=Rs x
  Profit=Rs 5000
  Ratio= 6000:x
  share of B =Rs 2000
  Therefore, 2000 = 5000x / (6000+x)
  2= 5x/ (6000+x)
  12000+2x =5x
  3x =12000
  x=4000 Rs

• by alligation method
  16 20
  
  17
  
  3 : 1
  so the ratio is 3:1

• 1>a
  profit ratio is a:b=3:2
  so if a invest 6000 b=4000
  
  2>a
  3*16+20=68
  68/4=17

• Let proportion of 16 carat=x
  Let proportion of 20 carat=y
  total proportion=(x+y)
  then (16x+20y)/(x+y)=17
  x=3y
  x:y=3:1

• A and B invested money in the ratio = 6000 : x
  profit is 5000
  so B's share is x/(6000+x) *5000 = 2000
  put the values(try options) in above expressions check it .for x=4000 u will get 2000
  so answer is 4000

• 6000×12:x×12
  6000:x
  (X÷x+6000)×5000=2000
  5x=2(x+6000)
  5x=2x+12000
  3x=12000
  X=4000
