in what proportion must rice that costs Rs.20/kg be mixed with rice that costs Rs.25/kg so that the mixture is worth Rs.22/kg

• 3:2
  
  If 'x'Kg. of rice of Rs. 20/Kg is added to 'y'Kg. of Rs. 25/Kg, then
  Per Kg. cost of a mixture=20x+25y/(x+y)=22, 2x=3y, x/y=3/2

• 3:2 we take 3 kg of rs:20 and 2kg of rs: 25
  then total=rs110 for 5kg
  here is also 110 for 5 kg
  so 3:2
