How many chocolates you can get in Rs.45

Question

Cost of one chocolate is Rs.1 and as a special promotion scheme you get 1 toffee for three wrappers. How many chocolates you can get in Rs.45?

Answer 1

1. Rs 45 = 45 chocolates (it will result of 45 wrappers)
2. 45 wrappers = 15 chocolate (it will result in additional 15 wrappers)
3. 15 wrappers = 5 chocolate (it will result in additional 5 wrappers)
4. 3 wrappers = 1 chocolate (it will result in 1 wrapper + 2 remaining from step 3)
5. 3 wrappers = 1 chocolate (it will result in additional 1 wrapper but we have to throw it)

Total = 45+15+5+1+1 = 67

Answer 2
