Question

1. In what ratio must rice at Rs 8.60 per kg be mixed with rice at Rs 11.40
per kg so that the mixture be worth Rs 10.20 per kg ?​

Answer 1

Answer:

10:13

Step-by-step explanation:

11.40-10.20    :       10.20-8.60

1.20               :         1.60

10                   : 13

Answer 2

The ratio must be 5:19.

Step-by-step explanation:

Since we have given that

Cost of first type of rice = Rs. 8.60 per kg

Cost of second type of rice = Rs. 11.40 per kg

Cost of mixture = Rs. 10.20 per kg

so, using "Mixture and Allegations", we get that

First type      Second type

  8.60                11.40

             12.40

---------------------------------------

12.40 - 11.40  :      12.40 - 8.60

  1                  :          3.8

  10                :          38

   5                 :          19

Hence, the ratio must be 5:19.
