Answer 1

The buying price is :

1 rupee

The selling price is :

150%

150/100 × 1 = 1.5

Each chocolate is :

1.5/3 = 0.5

Answer 2

Answer:

2 chocolate

Step-by-step explanation:

Since, he bought 3 chocolate for 1 rupee,

⇒ The cost price of 1 chocolate = $\frac{1}{3}$

Gain percentage = 50 %,

Gain in one chocolate = 50 % of cost price of one chocolate

$=\frac{50\times 1/3}{100}$

$=\frac{50}{300}$

Selling price of one chocolate = cost price of 1 chocolate + Gain

$=\frac{1}{3}+\frac{50}{300}$

$=\frac{100+50}{300}$

$=\frac{150}{300}$

$=\frac{1}{2}\text{ rupees}$

The number of chocolate should be sold in 1/2 rupees = 1 chocolate

⇒ The number of chocolate should be sold in 1 rupees = 2 chocolate.
