Take 225 common,
= 225 (20 + 21 + 22)

A. 41/3 hours
B. 42/11 hours
C. 38/5 hours

24. Two articles are sold for ₹9720 each. On one, the seller gains 8% and on the other, he loses 10%. What is his overall gain or loss?
A. Rs 380 gain
B. Rs 360 gain
C. Rs 380 loss
D. Rs 360 loss
Solutions
Selling price of the article sold at 8% gain = (108/100)× CP1
9720 = (108/100)× CP1
CP1 = ₹9000
Selling price of the article sold at 10% loss = (90/100)× CP2
9720 = (90/100)× CP2
CP2 = ₹10800
Total cost price of two articles = CP1 +CP2
= 9000+10800 = ₹19800
Total selling price of two articles = ₹19440
Net Loss = 19800 − 19440 = ₹360

Solutions
Let the consecutive even numbers be 2x, 2x + 2, 2x + 4, 2x + 6, 2x + 8, 2x + 10 and 2x + 12
So, according to question,
1.40 x 2x = 2x + 12
2.8x – 2x = 12

28. A number when divided by 112, leaves 31 as remainder. When the same number is divided by 14 and 16, leaves remainder as A and B respectively. What is the ratio of A and B?
A. 5: 1
B. 2: 3
C. 3: 2
D. 1: 5
Solutions
Let the number be N and quotient be k.
Number = (Divisor × Quotient) + Remainder
N =112k +31
= (14×8) + (14×2) + 3
A = 3
Again N = 112k + 31
= (16×7) + (16×1) + 15
So, B = 15
Required ratio = 3: 15 = 1: 5
29. A is more efficient than B and they together can complete a work in 24 days. Had A done 50% of the work and then B, the remaining work, then the work would have been done in 50 days. B alone will complete 40% of the same work in:
A. 16 days
B. 24 days
C. 21 days
D. 20 days
Solutions
Best Method to solve this question is by options.
Consider option A
If B alone will complete 40% of the same work in 16 days
Let total work = 120 unit
Efficiency of B = 3 unit
Efficiency of A+B = 5 unit
Efficiency of A = 5-3 = 2unit
But according to question A is more efficient than B.
So, option A is wrong.
Consider option B.
If B alone will complete 40% of the same work in 24 days
Let total work = 120 unit
Efficiency of B = 2 unit
Efficiency of A+B = 5 unit
Efficiency of A = 5-2 = 3 unit
Now, If A done 50% of the work and then B do the remaining work
30. Two cars, A and B, participated in a race of 1200 km. Speeds of car A and car B are 100km/hr and 120 km/hr, respectively. Car B gives Car A a head start of T hours. But car A has a nitro-boost, which increases its speed by 25% for one hour. If both cars reach the finish line at the same time, then find T.
A. 2.5 hours
B. 1.75 hours
C. 2 hours
D. 1.5 hours
Solutions
Distance travelled by A (to travel in one hour) with nitro boost = 100 × 125/100 = 125 km
Remaining distance = 1200 – 125 = 1075 km
Time taken to travel the remaining distance = 1075/100 = 10.75 hours
Total time taken by A to reach the finish line = 11.75 hours
Time taken by B to reach the finish line = 1200/120 = 10 hours
Therefore, head start given by B to A = T hours = 11.75 – 10 = 1.75 hours

35. Seven years from now, Virat will be twice as old as Mohinder. Five years ago Mohinder’s age was one year less than 2/5th of Virat’s age. What is Virat’s present age?
A. 53 years
B. 57 years
C. 51 years
D. 55 years
Solutions
Let present age of Virat and Mohinder are X years and Y years respectively.
After seven years, virat’s age = X+7 and Mohinder’s age = Y+7.
It is given that it will be twice of mohinder’s age.
So, X+7 = 2 (Y+7)
X = 2Y+7 —-eqn (1)
Five years ago,
(Y-5) = 2/5 (X-5) – 1
5(Y-5) = 2X-10 -5
5Y-25 = 2X-15
5Y = 2X+10 —-eqn (2)
Now, putting value of X in eqn 2
5Y = 2(2Y+7) +10
5Y = 4Y+ 24
Y = 24
X = 2 x 24 + 7
X = 48 + 7
X = 55
36. A man starts running from point P at 11:00 AM with a speed of 10 km/hr. He runs for 2 hours and then takes a 1 hour rest. He continues this till he is caught by another man who starts at 2:00 PM from point P and runs non-stop at a speed of 15 km/hr towards the first man. At what time (in PM) will the first man be caught?
A. 6:20
B. 4:40
C. 6:00
D. 5:30
Solutions
Since the first person takes rest after every 2 hours, he will travel from 11 AM – 1 PM and then takes rest for 1 hour from 1 PM – 2 PM .
Distance covered by Ist person from 11 am- 2pm= 10*2= 20 km
In next 2 hours 2pm-4pm distance covered = 10*2 = 20 km
Total distance covered by Ist person = 40km
Now rest is taken from 4pm – 5pm
In these 2 hours IInd person travelled = 15*2 = 30km
Now the remaining 10 km is covered from 4pm-5pm as Ist one is taking rest in this time.
Now 10 km is covered in 10/15 hours = 2/3 hours = 40 minutes
So, both of them meet at 4:40pm
Short Trick:-
In the first three hours, the first man covered 20 km distance. In the next 2 hours, from 2 pm to 4 pm, he covered 20 km more and then was taking rest for the next 1 hour.
Thus total distance covered = 40 km
The second man covers 30 km distance in the first 2 hours and then he takes
= 40 more minutes to catch the first person.
Thus, total time taken by him = 2 hours 40 minutes
Since he started at 2 pm, he catches the first man at4:40 pm
37. Three unbiased coins are tossed once. Find the probability of getting exactly 2 tails.
A. 3/5
B. 2/3
C. 3/8
D. None of the above
Solutions
We know that,
Probability of occurrence of an event

Now, when fourth friend N joins then,
K+L+M+N = 23 × 4 = 92 ….(ii)
So, Age of fourth friend (N) = 92 – 72 = 20 yrs.
Age of R = 20 + 2 = 22 yrs.
Now, R replaces K then the average age becomes-
R+L+M+N = 22.5 × 4 = 90 …. (iii)
So, L+M+N = 90 – 22 = 68
Thus, K + 68 = 92 (from ii)
K = 24 years.
