Step-by-step explanation:

Cost price of one lock = 34 / 8 = Rs 4.25

Selling price of one lock = 57 / 12 = Rs 4.75

Profit got by selling one lock = Selling price - Cost price = 4.75 - 4.25 = Rs 0.50

The shopkeeper makes 50 paise profit by selling one lock. In order to make Rs 45 profit, he/she needs to sell 45/0.5 = 90 locks
