Answer 1

Answer:

Ratio of CP and SP will be CP:SP = 100:85

Step-by-step explanation:

Concept: Loss% is Loss expressed a percentage of CP

Loss = CP - SP

Loss% = 100*[(CP - SP)/CP]

Loss% = 100*[1 - (SP/CP)]

Given Loss% = 15

=> 15 = 100*[1 - (SP/CP)]

=> 0.15 = 1 - (SP/CP)

=> 1 - (SP/CP) = 0.15

=> (SP/CP) = 1 - 0.15

=> SP/CP = 0.85

=> SP/CP = 85/100

=> CP/SP = 100/85

=> CP:SP = 100:85

Ratio of CP and SP = 100:85
