Answer 2

Answer:

19. 2%

20. 4% gain

Step-by-step explanation:

they're very simple.

19.

cost is 980. profit is made on cost. so,

980 + 10% = 1,078

marked price is 1100.

1% of 1100 is rs 11.

the difference between 1100 & 1078 is rs 22.

so, 22 ÷ 11 = 2%

20.

cost not given. but we'll assume cost as 100 (you can assume anything but 100 is convenient).

so he marked the book 30% above cost (cost being rs 100 in our assumption) , which is 100 + 30% = 130.

then he allows a discount of 20%.

so, 130 - 20% = rs. 104.

as we were assuming cost price to be 100, and he finally got 104 , it's a profit of rs4 which is 4% of cost.

so it's a 4% gain.
