Question

Mr chaddha bought some kg of rice for ₹60 per kg and an equal quantity of rice for ₹ 30per kg. if he mixed both kind of rice together and sells at ₹70 per kg. Find his gain or loss %?

Answer 1

Consider he purchased 100 kgs rice

so for 1st rice he paid 6000

and 2nd rice he paid 3000

totally he purchased 200 kgs rice for 9000

which is 4500 for 100 kg

SP=7000     and    CP = 4500

so profit P = 2500

profit % = $\frac{profit}{CP}*100$

so profit % = $\frac{2500}{4500} * 100$

= 55.5556 %

so overall profit of 55.556%

Hope that helps you!!
