"72",
"108",
"66",

] | B | First round distance travelled (say) = d
Speed = 80 k/h
Time taken, T2 = d/80 hr
Second round distance traveled = d (same distance)
Speed = 120 k/h
Time taken, T2 = d/120 hr
Total time taken = 3 hrs
Therefore , 3 = d/80 + d/120
LCM of 80 and 120 = 240
3= d/80 + d/120

At 6'o clock clock ticks 6 times. The time between first and
last ticks was 30sec. How much time it takes at 10'o clock. | [
"66sec",
"54sec",
"62sec",
"64sec"
] | B | At 6'0 clock, clock ticks 6 times.
So, there must be 5 intervals between clock ticks.
Time Between first and last ticks = 30sec
So, 1 interval = 30/5 = 6sec
So 6'o clock 5 *6=30sec
7'o clock 6 *6=36sec
.
.
9'o clock 8 *6=48sec
10'o clock 9 *6=54sec
So, 54sec at 10'o clock.

A man takes twice as long to row a distance against the stream as to row the same distance in favour of the stream. The ratio of the speed of the boat in still water and stream is | [
"3:1",
"None of these",

Let speed downstream = x kmph
Then Speed upstream = 2x kmph
So ratio will be,
(2x+x)/2 : (2x-x)/2
