Question

36. a producer blends two qualities of rice, one costing rs. 12.50 per kg and the other costing rs. 14.00 per kg. in the ratio of 4 : 5. find his profit percent if he sells the mixture at the rate of rs. 16 per kg.

Answer 1

The profit percent is 120% (Or the increase is 20% depending on how your answer must be formatted)

Begin by multiplying the ratio by the price values. 12.50(4) + 14.00(5)

This gives 50+70, which is rupees 120 /9 kg

Next, you divide by the 9 kg, so that you can find the price per kg

This gives you a rate of rupees $13\frac{1}{3}$ per kg.

Next, you must divide the price that it is being sold at for the price that it cost. This will be $\frac{16}{13\frac{1}{3}}$

This simplifies to $\frac{1.20}{1}$

Next you convert this to a percentage by moving the decimal 2 places to the right. This gives you a 120% profit percent

Answer 2

Answer:

20%

Step-by-step explanation:

let the ratio terms be x

(12.50*4x)+(15*5x)

50x+70x=120x

120x/4x+5x

120/9x

16*(4x+5x)

16*9x

144x

CP=120x

SP=144x

PROFIT=24x

PROFIT%= sp/cp *100

              = 24x/120x*100

              = 1/5*100

              = 20 %
