Question

17 Arthur, having bought a cricket-ball for £1.25, sold it to Bill at 20% profit. What did Bill pay?

18 Bill (in no. 17) was short of money and sold the ball to Charlie at a loss of 20%. What did Charlie pay?​

Answer 1

Answer:

17. Bill paid 1.50 euro.

18. Charlie paid 1.20 euro.  [bill suffered a loss of 0.30 ]

Explanation:

20% profit is gained on 1.25 and the sum becomes 1.25 + 20/100*1.25 =1.50

whereas, the loss is 20% of 1.50 and so, 1.50- 20/100*1.50 = 1.20.
