aquarat_48937 | aquarat | Two trains of length 120 m and 280 m are running towards each other on parallel lines at 32 kmph and 30 kmph respectively. In what time will they be clear of each other from the moment they meet? | [
"A)33 1/5 sec",
"B)23 1/5 sec",
"C)24 1/5 sec",

aquarat_42971 | aquarat | In a covering a certain distance, the speeds of A and B are in the ratio of 3:4. A takes 30 minutes more than B to reach the destination. The time taken by A to reach the destination is? | [
"A)32 hrs",
"B)8 hrs",
"C)2 hrs",

Ratio of times taken = 4:3
Suppose A takes 4x hrs and B takes 3x hrs to reach the destination.
Then, 4x - 3x = 30/60 => x = 1/2
Time taken by A = 4x hrs = 4 * 1/2 = 2 hrs.

"A)I only",
"B)II only",
"C)I and II only",

(xy – 6)(xy + 4) = 0
xy – 6 = 0 or xy + 4 = 0
xy = 6 or xy = -4
Since we need y in terms of x, we can isolate y in both of our equations.
y = 6/x or y = -4/x

aquarat_23990 | aquarat | P, Q and R can do a work in 20, 30 and 60 days respectively. How many days does it need to complete the work if P does the work and he is assisted by Q and R on every third day? | [
"A)10 days",
"B)14 days",

Amount of work P can do in 1 day = 1/20
Amount of work Q can do in 1 day = 1/30
Amount of work R can do in 1 day = 1/60
P is working alone and every third day Q and R is helping him
Work completed in every three days = 2 × (1/20) + (1/20 + 1/30 + 1/60) = 1/5
So work completed in 15 days = 5 × 1/5 = 1
