If Cp = Rs 660, Loss percent = 5% find Sp

Aneli [31]

Answer:

SP = 627 Rs

Step-by-step explanation:

Percentage loss is calculated as

$\frac{CP-SP}{CP}$ , then

$\frac{660-SP}{660}$ = 5% = 0.05 ( multiply both sides by 660 )

660 - SP = 33 ( subtract 660 from both sides )

- SP = - 627 ( multiply both sides by - 1 )

SP = 627 Rs

The pair of segments on the right tells you the ratio of the segment length above the horizontal line to that below the horizontal line is ...

18 : 6 = 3 : 1
