A. 20/6 hours
B. 27/2 hours
C. 30 hours
D. 30/13 hours
Explanation:
Speed downstream = 20 + 6 = 26 kmph.
Time required to cover 60 km downstream = d/s = 60/26 = 30/13 hours.
A. Rs.600
B. Rs.500
C. Rs.400
D. Rs.300
Explanation:
Sum be Rs.100
S.I = Rs.(1000/100) =Rs.10
C.I = Rs.[{100 × (1 +5/100) 2} – 100] =Rs.41/4
Difference C.I amd S. I = Rs.(41/4 – 10) =Rs.25
25 : 1.50 : : 100 : x
Therefore x = ((1.50 ×100)/25) = Rs.600

Answer: Option D
Explanation:
Let the required number of bottles be x.
More weavers, More mats (Direct Proportion)
More days, More mats (Direct Proportion)
| Wavers | 4 | : | 8 | :: 4 : x | |
| Days | 4 | : | 8 |
4 x 4 x x = 8 x 8 x 4
| x = | (8 x 8 x 4) |
| (4 x 4) |
x = 16.

Answer: Option C
Explanation:
Investment = Rs. [20 x (50 – 5)] = Rs. 900.
Face value = Rs. (50 x 20) = Rs. 1000.
| Dividend = Rs. | 27 | x | 1000 | = Rs. 135. | ||
| 2 | 100 |
| Interest obtained = | 135 | x 100 | % | = 15% | |
| 900 |

[D].
Answer: Option D
Explanation:
Let the numbers be 3x and 4x. Then, their H.C.F. = x. So, x = 4.
So, the numbers 12 and 16.
L.C.M. of 12 and 16 = 48.
