A man travels at a rate of 25m/sec. If he travels for 10½hrs, how many kilometres has he covered?
262.5
945
970
995
1822.9
Correct answer is B
No explanation has been provided for this answer.
The radii of two similar cylindrical jugs are in the ratio 3:7. Calculate the ratio of their volumes
1 : 04
3 : 07
9 : 49
0.086111111
27 : 343
Correct answer is E
radius ratio volume
r = \(r^3\)
so that
3 : 7 = \(3^3 : 7^3\) = 27 : 343
Simplify the expression: \(Log_{4}16\) + \(Log_{3}27\) + \(Log_{8}4096\)
-9
\(\frac{1}{3}\)
\(\frac{1}{9}\)
3
9
Correct answer is E
WHERE:
\(Log_{4}16\) = 2
\(Log_{3}27\) = 3
\(Log_{8}4096\) = 4
: 2 + 3 + 4 = 9
