Answer 1

Answer:

Hope it will help you

Step-by-step explanation:

profit = 15%

cp = 120kg of rs 24

120×24 = 2880

cp = 180 kg of sugar rs 28

180×28 = 5040

Total cp of sugar = 2880+5040 = 7920

Sp = (100+ gain%)/100 × cp

100+15/100×7920

115/100×7920

sp = 8808

This is your answer

Answer 2

Given,

120 kg of sugar of Rs.24 per KG and 180 kg of sugar of Rs.28 per KG is mixed.

To Find,

The selling price of the mixed sugar, such that a gain of 15% is received.

Solution,

The total Sugar to be sold = 120 + 180 = 300 kg

The actual cost of the sugar = (120×24)+(180×28) = 2880+5040 =  7920

Now since a gain of 15%

⇒ the total selling price of the sugar = $7920 (1 + \frac{15}{100})$ = 9108

Thus the selling price per kg sugar = $9108/300$ = 30.36

Henceforth the selling price of sugar per kg = Rs.30.36
