A) No profit, no loss B) 5%
C) 8% D) 10%

Answer 1

total c. p. =26*20 +30*36

=520+1080

=1600

s.p. =30*56

=1680

profit% =80*100/1600

=5% ans. b

Answer 2

Answer:

5% gain

Step-by-step explanation:

To get the gain or loss we need to get the cost of the rice and the selling price of the rice.

The Initial cost of the variety of the rice :

26 × 20 = Rs 520

30 × 36 = Rs 1080

The total initial cost = 1080 + 520 = Rs 1600

The selling price will be the total selling cost of the mixture.

Total amount = 26 + 30 = 56 kgs

Cost per kg = 30 per kg.

The tot cost = 56 × 30 = Rs 1680

From this we see that there is a gain.

The profit is therefore :

1680 - 1600 = 80

80/1600 × 100% = 5%

The gain is 5%
