Question

find SP when: CP equals to rupees 800 and loss equals to 5.5%​

Answer 1

Answer:

Step-by-step explanation:

SP = CP(100-percent loss)/100

= 800( 100-5.5)/100

= 756

Answer 2

Answer:

SP = Rs.756

Step-by-step explanation:

L% = percentage loss  = 100*(Loss/CP)

     = 100 * [(CP - SP)/CP]

     = 100 * (1 - (SP/CP))

L%/100 = 1 - (SP/CP)

SP/CP = 1 - (L%/100)

SP = CP*( 1 - L%/100)

Substituting for CP = 800 and L% = 5.5, we get:

SP = 800 * (1 - (5.5/100))

     = 800 * (1 - 0.055)

      = 800 * (0.945)

      = 756

Selling price = Rs.756

Verify:

CP = 800

SP = 756

Loss = CP - SP = 44

L% = 100*(44/800)

     = 5.5
