A. 64
B. 60
C. 50
D. 62

View Answer	Favorite Question

Answer: Option A

Explanation:

Sum of 10 integer is 462. The average of first 4 number is 52 and the average of last 5 number is 38. What is the fifth number ?

Sum of first 4 number = 4 X 52 = 208
Sum of last 5 number = 5 X 38 = 190
So, sum of 9 number = (208 + 190) = 398

So, the 5th number = (462 - 398) = 64 (Ans:)

A. 0°
B. 10°
C. 5°
D. 20°

View Answer	Favorite Question

Answer: Option B

Explanation:

At 4:20, the minute hand is on the 4, and the hour hand is 20/60 = 1/3 of the way from the 4 to the 5. Since the numbers on the clock are 360/12 = 30 degrees apart, the smallest positive angle between the hands at 4:20 is 30(4 1/3 - 4) = 30(1/3) = 10 degrees.

So, area = 10×68 = 680

Cost of fencing = ( 10×2×50) + ( 68×2×50) = Tk.7800 ( correct answer)

2771 . The area of a rectangle is 200 sq. meter . If the length is twice the breadth , what is the perimeter of the rectangle ?

A. 40
B. 50
C. 60
D. None of these

View Answer	Favorite Question

Answer: Option C

Explanation:

Let L be the length and B be the breadth.

So, L x B = 200

or, 2B x B = 200

or, B2 = 100

or, B = 10

So, L = 2B = 2 x 10 = 20

Therefore, the perimeter of the rectangle = 2 (L + B) = 2 (20 + 10) = 2 x 30 = 60.

D. 50

View Answer	Favorite Question

Answer: Option A

Explanation:

Let L be the length and B be the breadth.

So, L x B = 200

or, 2B x B = 200

or, B2 = 100

or, B = 10

So, L = 2B = 2 x 10 = 20

Therefore, the perimeter of the rectangle = 2 (L + B) = 2 (20 + 10) = 2 x 30 = 60.
