Question

The shopkeeper charged 12 rupees for a bunch of chocolate but i bargained to shopkeeper and got two extra ones, and that made them cost one rupee for dozen less then first asking price: How many chocolates I received in 12 rupees? a) 10 b) 16 c) 14 d) 18

Answer 1

Answer: b)16

Step-by-step explanation:Let the no of chocolates = x = x / 12 dozen

Price of x/12 dozen is Rs. 12

So price of 1 dozen is 144/x

Now we can also use the Second Condition:

144 / (x+2)  + 1 = 144 / x

x = 16

Answer 2

Let the no of chocolates = x

In case of saying in dozen,

1 dozen = 12 nos

⇒ Number of chocolates = x/12

Given,

• Price of x/12 dozen = Rs 12

So,

• Price of 1 dozen =  144/x

[144/(x+2)] + 1 = 144/x

⇒ x = 16

∴ Number of chocolates received = 16 chocolates(b)
