Mayank buys some candies for Rs 15 a dozen and an equal number of different c

Let the number of

Let the number of dozens of candies he bought of each variety be x
Hence total cost = 12x + 15x = 27x
Total selling price = 16.50*2x = 33x
Profit = 33x - 27x = 6x
Given 6x = 150 => x = 25
Hence he bought 50 dozens of candies in total

Choose the correct option.

Out of the shirts produced in a factory, 15% are defective, while 20% of the rest are sold in the domestic market. If the remaining 8840 shirts are left for export, then the number of shirts produced in the factory is

A13600

B13000

C13400

D14000

Explanation:

Let the total number of shirts be x.
Hence number of non defective shirts = x - 15% of x = 0.85x

Number
of shirts left for export = No of non defective shirts - number of
shirts sold in domestic market
= No of non defective shirts - 20% of No of non defective shirts
= 80% of No of non defective shirts

Hence 8840 = 0.8 * (0.85x) .
Solving for x we get, x = 13000
