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

575 . 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	Report

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%

A. 15/2 gallons
B. 17/2 gallons
C. 19/2 gallons
D. 19/2 gallons
E. 8 13 gallons

View Answer	Favorite Question	Report

20% of 125 gal = 0.20 × 125 gallon = 25 gal water

Lets add w gal water such that the water content is raised to 25%

so, 25 + w = 0.25 (o 125 + w)

25 + w = 31.25 + . 25w

w - 0.25w = 31.25 - 25

0.75 w = 6.25

w = 8.33 বা 8 1/3

A. 18
B. 20
C. 25
D. 30

View Answer	Favorite Question	Report

Answer: Option D

Explanation:

3 women can do as much work as 2 men

∴ efficiency of women to do a piece of work, e2 = (1/3)

∴ efficiency of men to do a piece of work, e1 = (1/2)

We know,

Total work done = (no. of men or women) * (no. of days) * (no. of hours) * (efficiency)

Therefore,

m1 * d1 * h1 * e1 = m2 * d2 * h2 * e2

or, 15 * 21 * 8 * (1/2) = 21 * d2 * 6 * (1/3)

or, d2 = 30 days .
