Question

In what proportion of sugar of 12 Rs /kg, Rs 14 / kg and Rs 20
Ikg should the mixture be Rs 15 / kg?

Answer 1

Step-by-step explanation:

the answer is 5:5:4

for proving this we take the LCM of 12, 14 , 15 , and 20

the LCM is 420

now let, we purchase sugar of 420 rs at the rate of 15

the quantity will be in kg

[tex]420 \div 15 = 28kg[/tex]

tex]420 \div 15 = 28kg[/tex]so now if we purchase

10 kg at the rate of 12

the amount will be

[tex]12 \times 10 = 120rs[/tex]

and 10 kg at the rate of 14 the amount will be

10×14=140 rs

and 8 kg at the rate of 20 then the amount will be

8×20=160rs

the total quantity is =28kg

and total money is

total money is 120+140+160=420

hence we can say that those sugar should be mixed in the ratio of 10:10:8 or 5:5:4 to make it of 15/kg
