Answers & Explanations:

1. Ans-b
Both Deepak and Deepika are reaching B from A and then
returning . When Deepika overtakes Deepak, the distances traveled by both of
them are equal. Therefore, the times taken by them are inversely proportional
to their speeds.
Let Deepak take t minutes for travel, Deepika overtakes him.
As Deepika started 45 minutes after Deepak he takes t-45 minutes.
=> t/ (t-45) = speed Deepika / Speed Deepak =2
=>t=90 minutes
Therefore Deepika overtakes Deepak at 9 a.m + 90 minutes =
10.30 a.m
2. Ans-c
If the price of strawberries decreases by 10 %, Caitlin
would save 10 % of her money i.e. Rs 50 to buy the same amount as before in Rs
50, she can buy 2 kg more, therefore the current price of 1 kg strawberries is
Rs. 25.
This price is after 10 % deduction. Hence, original price =
25/0.9= Rs 27.77
3. Ans-c
Anil, Ashok, Ankit can be arranged in 3!= 6 ways out of
which only one is favorable.
Probability = 1/6
4. Ans-b
Solve through options
810/54 – 900/75= 3= (6-3=3)
Hence 4 days option b
5. Ans-c
The total persons in each hall= 25x(7/5)=35
Total number of chairs= 352= 1225
Maximum available capacity= 1225X0.8=980 chairs
6. Ans-b
(P + Q)will fill in 1 hour = (1/12 + 1/15) = 3/20 part
(P + Q)will fill in 1 hour = (1/12 + 1/20) = 2/15 part
Part filled in 2 hrs = (3/20 + 2/15) = 17/60
Part filled in 6 hrs = 3 * 17/60 = 17/20
Remaining part = 1 – 17/20 = 3/20
Now, it is the turn of P and Q and 3/20 part is filled by P
and Q in 1 hour.
Total time taken to fill the tank = (6 + 1) = 7 hrs.
7. Ans-d

In first case Rakesh travels 100 m and Ramesh travels 90 m
in the same time.
Therefore, the ratio of their speeds is 10:9
In the second case, Rakesh is travelling 110 m to reach the
finishing line. In the same
time, the distances travelled by both of them will again be
in the same ratio as their old speeds.
Distance Ramesh/Distance Rakesh = Speed Ramesh / Speed
=>Distance Ramesh/110=9/10
=>Distance Ramesh= 99m
Therefore Ramesh has travelled only 99 m when Rakesh reached
the finish
Hence Rakesh beats Ramesh by 1 m.
8. Ans- a
Let the total work = 100 units.
Abram’s one day work = 100/5= 20 units.
Abraham and Ashley’s 1 day work= ¾ x 20 = 15 units
Mitch and Harrison’s 1 day work= 1/5 x 20= 4 units
In one day all of them can do = 20+15+15+4+4= 58 units of
Hence they complete the work in 100/58 days.
9. Ans-b
Let price of 1 g be 1 rupee
They sell 1000g as 1100g
They will sell 1100 g as 1100/1000  x 1100= 1210 g
Which means they get rs 1210
Their profit percentage= [(1210-1000)/1000]x100= 21 %
10. Ans-a
Let the total number of plantings be x
plantings by Aniket= 5/8x
plantings by Sanket= 3/8x
survived plants of Aniket=1/3  of 
5/8  of x=  5x/24
died plants of Sanket= ½ of 3/8  of x= 3x/16
3x/16=27=> x=144

Plants survived  by
Aniket= 5x/24=30
