A) 250 kg

B) 320 kg

C) 420 kg

D) 360 kg

E) 480 kg

Correct Answer:
D) 360 kg

Description for Correct answer:
The quantity of rice sold at 20% loss = x kg.

The quantity of rice sold at 15% profit = (600 - x) kg

According to question,

\( \large x \times \frac{80}{100} + \left(600 - x \right) \times \frac{115}{100} = 600 \times \frac{94}{100} \)

\( \large 80x + \left(600 - x \right) \times 115 = 600 \times 94 \)

\( \large 80x + 69000 - 115x = 56400 \)

35x = 12600

x = 360kg
