Okay. I got this.

2/3 x 2 = 4/6
1/3 x 2 = 2/6

So basically, 2/3 is more than 1/3.
(Wait did I have to do the math?)

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
