View Answer	Favorite Question

Answer: Option D

Explanation:

100 টাকায় কমে 20 টাকা

1 টাকায় কমে 20/100 টাকা

∴ 12 টাকায় কমে (20/100 × 12 )

= 12/5 টাকা

এখন ২টি কলার বর্তমান মূল্য = 12/5 টাকা

1 টি কলার বর্তমান মূল্য = 12/5 × 2 টাকা

∴ 50 টি কলার বর্তমান মূল্য = (12 × 50) / (5 × 2)

= 60 টাকা

1383 . Ashraful has purchased a square sheet of plywood 169 square feet area. To cover a wall he must cut off 3 feet from a side. What is the area in square feet of the wall?

A. 154
B. 144
C. 196
D. 130

View Answer	Favorite Question

Answer: Option D

Explanation:

Ashraful has purchased a square sheet of plywood with an area of 169 square feet. Let's call the side length of the original square sheet "x" feet.

The area of the original square sheet is given as 169 square feet:

x^2=169

To find the side length "x," we take the square root of both sides:

√x=√169=13 feet

So, the original square sheet has a side length of 13 feet.

Now, Ashraful must cut off 3 feet from one side to cover a wall. This reduces the side length to 13−3=10 feet.

The area of the wall covered by the cut piece of plywood is:

10×13=130 square feet.

So, the area of the wall is 130 square feet. The correct answer is 130.

View Answer	Favorite Question

Answer: Option C

Explanation:

Let the average speed of slower and faster trains be S and (S + 6) miles/hr respectively.

Time taken = 10 am to 1:30 pm = 3.5 hr

Distance travelled by slower train = 3.5S

Distance travelled by faster train = 3.5(S + 6)

Now, 3.5S + 3.5(S + 6) = 287

or, 3.5S + 3.5S + 21 = 287

or, 7S = 287 - 21

or, 7S = 266

or, S = 266/7 = 38 miles/hr

So, speed of the faster train, S + 6 = 38 + 6 = 44 miles/hr
