Answer 2

Answer:

36

Step-by-step explanation:

Selling price of 1 chocolate: 160/90 = 16/9

for a loss of 20%, let the cost price be X

Therefore

[(100-20)/100]* X = 16/9

X =

$\frac{10}{8} \times \frac{16}{9 } = \frac{20}{9}$

now for a profit of 20%

Selling price of 1 chocolate =

$\frac{100 + 20}{100} \times \frac{20}{9} = \frac{24}{9}$

no. of chocolates for 96₹ to be sold =

$96 \div \frac{24}{9} = \frac{96 \times 9}{24} = 36$

36 chocolates
