MBA test preparations

1. At 12.5% simple rate of interest , in how many years the principal amount will be four times with interest.

Answer: Let the principal amount is Tk. 100

so, principal amount with interest = 100 × 4 = Tk. 400

So, interest = 400-100 = Tk. 300

At 12.5% interest or, 25/2% interest ,

Tk. 25/2 comes from 1 year

       1 comes from   2/25 year

    300 comes from =(2×300)/25 = 24 Years.

2. The monthly salary of a person increased by 10% in one month, but is decreased by 10% in the next month. What is the percentage increase or decrease in his original salary?

Answer: Let, salary of the person is Tk. 100

So, At increase of 10% salary = 100 × (1 × 0.1) = Tk. 110

Again, at a decrease of 10% salary = 110 × (1-0.1) = Tk. 99

So, Decrease in his original salary = (100-99) = Tk. 1

Percentage decrease of his original salary = 1%

3. Give the name of the countries to which the following Airlines?

1. Garuda 2. Lutfthansa 3. Airlanka
