# Rahul went to purchase a Nokia mobile handset, the shopkeeper told him to pay 20% tax if he asked the bill. Rahul manages to get the discount of 5% on the actual saleprice of the mobile and he paid the shopkeeper Rs. 3325 without tax. Besides he manages to avoid to pay 20% tax on the already  discounted price, what is the amount of discount that he has gotten?

 A) 750 B) 375 C) 875 D) 525

Explanation:

CP = 100, SP (with tax) =120

New   SP = 100 - 5 = 95

$\therefore$  Effective discount = 120 - 95 = 25

So, at SP of 95 ----> discount = 25

and      at SP of 3325 -----> discount = $\inline&space;\frac{25}{95}\times&space;3325=875$

Q:

12 days payment to the servant in a cloth showroom in festival season is Rs. 400 plus one shirt. The servant leaves after 9 days and recieves Rs. 280 and a shirt. What is the price of the shirt ?

 A) Rs. 80 B) Rs. 120 C) Rs. 70 D) Rs. 100

Explanation:

The servant worked for 9 days instead of 12 days, he should receive 9/12 of his total payment

Let the price of 1 shirt be Rs. S

i.e., 3/4 (400 + S).

However, the question states that the servant receive Rs. 280 + S where S is the price of the shirt.

By equating the two equations we get 3/4 (400 + S) = 280 + S.

Therefore, Price of the shirt S = Rs. 80.
