Answer: Option B
Explanation:
| Perimeter = Distance covered in 8 min. = | 12000 | x 8 | m = 1600 m. | |
| 60 |
Let length = 3x metres and breadth = 2x metres.
Then, 2(3x + 2x) = 1600 or x = 160.
Length = 480 m and Breadth = 320 m.
Area = (480 x 320) m2 = 153600 m2.
A. Rs.12000
B. Rs.14200
C. Rs.17520
D. Rs.13500
Explanation:
P = (184*106) / [6 2/3 * 6 2/3 *(300*6 2/3)]
P = 13500

Answer: Option C
Explanation:
l = 10 m,
h = 8 m.
So, r = l2 – h2 = (10)2 – 82 = 6 m.
Curved surface area = rl = ( x 6 x 10) m2 = 60 m2.
A. 10 seconds
B. 15 seconds
C. 20 seconds
D. 12 seconds
E. None of these
Explanation:
Speed of the boat downstream = 15 + 3 = 18 kmph
= 18 * 5/18 = 5 m/s
Hence time taken to cover 60 m = 60/5 = 12 seconds.
