A Certain variety of rice which costs 32 /- per kg is mixed with 12 kg of another variety of rice which costs 40 per kg and the mixture is sold at 49 per kg gaining a profit of 40%. Find the quantity of the mixture. Solution: Let the cost price of the mixture per kg be C. $C\times\dfrac {100+40}{100} = 49$ C = 35 So the ratio of the quantities of the first variety that of the second variety = 5: 3 The quantity of mixture = $\displaystyle 12\times\dfrac{8}{3} = 32$ what cost price formula is used in this solution?
