Answer 1

Answer:

q1:

i) Given:

Cost Price CP=Rs.950

Gain %= Profit %=6%

Consider the formula of Selling Price, SP.

SP=CP+CP×

100

6

=950+(950×

100

6

)

=950+57

SP= Rs. 1007

Hence, the required SP is Rs. 1007.

iii)CP = ₹ 1540, loss = 4% We have, SP = {((100 – loss %) /100) × CP)} = {((100 – 4) /100) × 1540)} = {(96 /100) × 1540} = 1478.40
