Question

3. a) b) If C.P. = Rs 640, S.P. = Rs 608, c) If C.P. = Rs 750, loss percent = 8% find S.P. Git porcent = 20%, find S.P.​

Answer 1

a) To find the selling price (S.P.) when the cost price (C.P.) is Rs 640 and the loss percentage is 20%, we can use the formula:

S.P. = C.P. - (Loss Percentage * C.P.)

Given that the loss percentage is 20% (0.20 as a decimal), we can substitute the values:

S.P. = 640 - (0.20 * 640)

S.P. = 640 - 128

S.P. = Rs 512

Therefore, the selling price is Rs 512.

b) To find the selling price (S.P.) when the cost price (C.P.) is Rs 750 and the gain percentage is 8%, we can use the formula:

S.P. = C.P. + (Gain Percentage * C.P.)

Given that the gain percentage is 8% (0.08 as a decimal), we can substitute the values:

S.P. = 750 + (0.08 * 750)

S.P. = 750 + 60

S.P. = Rs 810

Therefore, the selling price is Rs 810.
