Question

A shopkeeper gives a chocolate for re.1 and a chocolate for wrappers of same chocolate. how many chocolates you can buy from rs 75? ans::112

Answer 1

The cost of each chocolate is Re 1.

For Rs 75 he can purchase 75 chocolates.

So now he has 75 wrappers.

for 3 wrappers he gets 1 chocolate.

So for 75 wrappers he gets 65/3 = 25 chocolates.

Now he has 25 wrappers.

He can exchange 24 wrappers for 24/3 =8 chocolates & 1 wrapper is still with him.

After eating 8 chocolates he has 8 + 1 = 9 wrappers.

He exchanges these 9 wrappers for 9/3 = 3 chocolates.

Again he has 3 wrappers so he gets 1 more chocolate.

Total chocolates he can get

= 75 + 25 + 8 + 3 + 1

= 112 chocolates.

Please see:

As the answer was given i have used 3 wrappers for exchange of 1 chocolate.
