lose ?
a) Gain 7.14%
b) Loss 7.14%
c) Gain 6.14%
d) Loss 6.14%
​

Answer 1

Answer:

a) Gain 7.14%

Step-by-step explanation:

Cost of 5 roses = 10

Hence cost of 7 roses = ( 10/5 ) × 7

Cost of 7 roses = 14

Profit = SP - CP

Profit = 15 - 14

Profit = 1

Profit% = ( profit / CP ) × 100

Gain% = ( 1 / 14 ) × 100 = 7.14%
