Answer
Answer:
Padma purchased 30 kg of rice at the rate of tk 17.50
(17.50 * 30)=525 Tk
another 30 kg rice 30 * X=30X
So, Cost Price of 60 kg Rice = (30X + 525) Tk
And sold 18.60 per kg and made 20% overall profit
(60 * 18.60)=1116
Now,
(30X + 525) + (30X + 525)*1/5 =1116
⇒ 30X + 525 +6X + 105 =1116
⇒ 36X +630 =1116
⇒ 36X = 1116-630
⇒ 36X = 486
⇒ X =486/36 = 81/6


∴ X = 6|81|13.5
              6
