1. Profit at a price = loss at  other price => CP must be numerically between those prices
CP = (56+42)/2 = Rs. 49.

2. Gain % = 1000/880 => 1. 1363 => 13.63%

3. For P, SP=1080 and loss=10% => CP = 1080/0.9 =1200 => loss = 1200-1080 = 120.
For Q, SP=1800 and loss=10% => CP = 1800/0.9 = 2000 => loss = 2000-1800 = 200.

4. She got profit => profit % = 15/10 X 12/12 = 1.5 => 50%.

5. Profit % = 19 1/21 => 1.19047.
Let he measure x cm for 100 cm. Then, 100/x = 1.19047 => x=84 cm
So he measures 16 cm less for every meter.

6. Loss = 30% on CP i.e., 0.3CP => SP = 0.7CP
Loss % on SP = loss/SP X 100 = 0.3CP/0.7CP X 100 = 42.85%.

7. Total CP = 90000 & total SP = 93000 => gain = SP/CP = 93000/90000 =1.0333 = 3.33%

8. Total cost of a watch = 180 + (500/100) = 185.
Gain = 20% => SP = 1.2CP = 1.2 X 185 = 222

9. 0.75 MP = 0.8 CP (since 20% loss)
So, MP = 1.0666CP => 6.66% gain

10. 1.2 X 1.25 X 0.6666 X CP = 1000 => CP = 1000 (profits of 20%, 25% & loss of 33.33%)
