Sulekha bought 36 kg of sugar for ₹1,040. She sold it at a profit equal to the selling price of 10 kg of it. What is the selling price (in ₹) for 5 kg of sugar ?
Answer & explanation
Correct answer: option 4
Cost price of 36 kg = Rs.1040
CP of 1 kg sugar = \(\frac{1040}{36}\)
Now,
SP × 10 = SP × 36 - CP × 36
CP × 36 = 26 × SP
\(\frac{1040}{36}\) × 36 = 26 × SP
1040 = 26 × SP
SP = \(\frac{1040}{26}\) = 40
SP of 5 kg sugar = 40 × 5 = 200
