3
Find the selling price, when:
(iii) CP= 645 and loss%=13-%​

Answer 1

Answer:

Step-by-step explanation:

2)

CP = 2400 and gain%= 5%

Gain%= SP-CP/CP × 100

5=SP-2400/2400 × 100

5×2400/100= SP - 2400

120=SP-2400

120+2400=SP

SP=2520

3)

CP= 645 and loss%=13%

Loss%= CP-SP/CP×100

13=645-SP/645 ×100

13×645/100 = 645-SP

83.85=645-SP

SP= 645-83.85

SP=561.15
