Let x be the cost of 20 units, then 1 rupee is (100%-25%)= (75%) of x.
Given that 1 rupee = 100paise:

x=133.33 paise
The cost of 20 units should be 133.33 paise.

From the condition, 20 flowers were bought for a rupee. Hence, the price for each flower was = 5 paise when bought. To gain 25%, 20 flowers should be sold for 125 paise. It means that each of the 20 flowers should be sold for = 6.25 paise. Therefore, the number of flowers to sell for a rupee is = 16. ANSWER. 16 flowers should be sold for a rupee.
