​

Answer 1

Answer:

48 kg

Explanation:

Cost per kg = (42*5 + 63*2)/7

                    = 48 kg

Step-by-step explanation:

Answer 2

Given:

Price of the first type of pulses, P1= Rs. 42/ kg

Price of the second type of pulses, P2= Rs.63/ kg

Mixing ratio=5:2

To find:

The cost of the new mixture

Solution:

We can find the cost by following a simple process -

We know that the concept of weighted average has to be applied in this question.

Weighted Average is the sum of prices multiplied by their ratio and then divided by the sum of ratios.

Cost of new mixture= (P1×5+ P2×2)/5+2

=(42×5+63×2)/7

=(210+126)/7

=336/7

=Rs. 48/ kg

Therefore, the cost of the new mixture is Rs. 48 per kg.
