Answer:
40 kg of rice = 6.75rs/kg
60 kg rice = 8rs/kg
Now combined price will be
w1 p1 + w2 p2/w1+w2 = 40(6.75)+60(8)/40+60
= 270+480/100
= 750/100
= 7.5Rs
Now let selling price be x
Given gain = 20%
Therefore, 20 = SP-CP/CP*100
20 = SP-7.5/7.5*100
7.5 = SP - 7.5
SP = 15 Rs/kg
Step-by-step explanation: Hope it helps
