Answer 1

Answer:

100 × 1.5 = Rs 150 is C.P of fan is the Ans.

Step-by-step explanation:

Ans Let C.P of an electric fan = Rs 100

Actual transaction

Profit = 10 %.Therefore S.P = 100 + 10 = Rs 110

Assumed transaction

C.P = 100 - 10 = Rs 90

Gain = 10 %.Therefore S.P = 90 + 10 % of 90 = Rs 99

Difference in actual and assumed S.P

= 110 - 99 = Rs 11

Applying unitary method

For Rs 11 difference in S.P, C.P = Rs 100

For Rs 1 difference in S.P, C.P = 100/11

For Rs 16.50 difference in S.P, C.P = ( 100/11) × 16.5

= 100 × 1.5 = Rs 150 is C.P of fan is the Ans
