George while driving along the highway saw road markers which are at equal distances from each other. He crosses the markers every 20 seconds. If he increases his speed by x meters per second, he crosses the markers at every 15 seconds. But if he increases his speed by y meters per second, he crosses the marker at every 10th second. If y-x = 40 meters per second, then what is the distance between two markers.
A1100
B1200
C1301
D1220
Answer: Option B
Explanation:Let speed be =z m/s then Distance= 20z m (z+x)15=20z; (z+y)10=20z
Also given that y - x = 40 solving we get 20z=1200

A70
B81
C90
D80

A5
B6
C9
D7
Answer: Option D
Explanation:Let the work be 60 units. If venky leave 3 days before the work, Last 3 days must be worked by Ravi.
So the remaining days of work be x days,
Total days to complete the work be x + 3 days.
Now Capacities of Rajiv is 60/10 = 6,
Venky is 5,
Ravi is 4. (6 + 5 + 4) 2 + (5 + 4) (x - 3) + 4 x 3 = 60.
30 + 9x - 27 + 12 = 60 9x - 15 =30
9x = 45 x = 5
So total days to complete the work = 2 + 5 = 7 days.
