Nihal bought 20kg of rice at ₹18 per kg and 25 kg of rice at ₹ 16 per kg . He mixed the two varieties and sold the mixture at ₹ 19 per kg. find his gain per cent in the whole transaction. ​

Answer 1

Step-by-step explanation:

20kg -= 18 rs

25kg= 16 rs

so total sell 20+25= 45 kg

20×18=360

25×16=400

cost price = 360+400=760

selling price:

45×19=855

gain% = 855-760=95

95÷760×100

= 12.5%
