55.00km/h
60.00km/h
67.50km\h
75.00km\h
Correct answer is C
Average speed from P to Q = 90km\h
Average speed from O to P = 45km/h
Average for the entire journey = 90 + 45
\(\frac{135}{2}\) = 67.50 km/h
0.8
0.9
1.1
1.2
Correct answer is C
\(\frac{0.021741 \times 1.2047}{0.023789}\) = \(\frac{0.022 \times 1.2}{0.024}\) (to 216)
= \(\frac{0.0264}{0.024}\)
= 1.1
39.93
35.00
33.00
30.00
Correct answer is D
1m = 1.1 yard, length(L)= 50m
= (50 x 1.1)yards
= 55 yards
Area(A) = length(L) y width (W)
1815 = 55y width (W)
width (w) = \(\frac{1815}{55}\)
= 33 yards
But 33 yards = 30 meters
120cm
240cm
360cm
480cm
Correct answer is B
The least length is \(\frac{40}{48}\) = \(\frac{5}{8}\)
for the rod to be cut in exactly equal trips
Ratio \(\frac{5}{6}\) : \(\frac{48}{40}\)
\(\frac{\frac{5}{6}}{\frac{40}{48}}\) = 1
\(\frac{5}{6}\) x \(\frac{48}{40}\) = \(\frac{240}{240}\) = 1
The least length = 240cm
Convert 241 in base 5 to base 8,
718
1078
1768
2418
Correct answer is B
2415 = 2 x 52 + 4 x 5 + 1 x 5 + 1 x 5o
50 + 20 + 1 = 7110
Convert 7110 to base 8
\(\begin{array}{c|c} 8 & 71 \\ 8 & 8 R 7\\8 & 1 R 0\\8 & 0 R 1\end{array}\)
= 1078
