Sulekha bought 36 kg of sugar for â‚¹1,040. She sold it at a profit equal to the selling price of 10 kg of it. What is the selling price (in â‚¹) for 5 kg of sugar ?

200

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
