Answer:

Answer 4 is 260

Answer 5 is cost of one pen is 5

Answer 6 is 12%

Explanation:

Answer 4.

Cost of 10kg rice is 325

then cost of 1kg is 325/10

hence 1 kg =32.5

the cost of 8kg = 8 × 32.5 =260

Answer 5.

Cost of 12 pen = 60

then cost of one pen = cost of 12 pens/no. of pen

I.e 60/12

hence the cost of 1 pen = 5

Answer 6

Cost price =400

Selling price = 448

Profit = spcp(i.e. 448-400)

Profit = 48

Profit percent = profit ×100/cost price

I.e 48×100/400

hence profit percent = 12
