Bangladesh Bank - Assistant Director - 2008

A. 29
B. 780
C. 979
D. 920

View Answer	Favorite Question

Answer: Option D

Explanation:

Hints: y is 10% more than 125

So, y = 125 + 10% of 125

= 125 + 10/100 × 125

= 125 + 12.5

= 137.5

x is 10% less than y

x = 137.5 - 10% of 137.5

= 137.5 - ( 10/100 × 137.5)

= 137.5 - 13.75

= 123.75

x = 123.75

566 . 100 oranges are bought at the rate of Tk. 350 and sold at the rate Tk. 48 per dozen. The percentage of profit or loss is :

A. 14.29% gain
B. 14.29% loss
C. 15% gain
D. 15% gain

View Answer	Favorite Question

Answer: Option A

Explanation:

100 oranges cost 350tk

So, 1 orange costs (350/100)=3.5 tk

12 oranges selling for 48 tk

So, 1 orange selling for (48/12)=4 taka

Profit in 3.5 taka=(4-3.5)=0.5 taka

So, profit in 350 taka=(350×0.5)/3.5=50 taka

Now, (50×100)/300=14.29%
