Find the answer to this tough Whatsapp Riddle.
There is a shop that reads:
Buy 1 for $10.00
10 for $20.00
100 for $30.00
I needed 740 and still only paid $30.00.
How can the shop-keeper still make profit?

The shop actually sells digits.
Per digit costs $ 10.
So as 740 also needs 3 digits like 100, the selling price remains the same.
