Directions: Read the following questions carefully and choose the right answer.
1
The marks scored by Prasoon Joshi in three subjects are in the ratio 4 : 5 : 6. Prasoon Joshi scored an overall aggregate of 60% in the exam. If the maximum marks in each subject are the same, in how many subjects did Prasoon Joshi score more than 70% marks?
» Explain it
A
Let the maximum marks in each subject be 100. 
 
∴ Prasoon joshi's total score = 60% of (100 + 100 + 100) = 0.6(300) = 180 
 
Also, 70% marks in a subject correspond to 0.7(100) = 70
 
Let Prashoon joshi have scored 4x, 5x and 6x in the three subjects.
 
∴ 4x + 5x + 6x = 180
 
∴ 15x = 180 i.e. x = 12
 
Hence, his marks in the three subjects are 48, 60 and 72 . 
 
Hence, he has scored more than 70 in exactly one subject. 
 
Hence, option A is correct.
2
Two trains running in opposite directions cross a pole in 33 seconds and 17 seconds respectively and cross each other in 27 seconds. What is the ratio of their speeds?
» Explain it
D
Let the speed of the trains be x and y m/s (meters per second) respectively.
 
∴ Length of first train = 33x and length of second train = 17y meters
 
Since the trains run in opposite directions, their relative speed = (x + y) m/s
 
∴ (33x + 17y)/(x + y) = 27
 
∴ 33x + 17y = 27x + 27y
 
∴ 6x = 10y
 
∴ x : y = 10 : 6 = 5 : 3
 
Hence, option D is correct

3
Two merchants sell an article for Rs.1,000 each. Merchant A computes his profit on cost price while Merchant B computes his profit on selling price. Both make a profit of 25% each. By how many rupees is the actual profit made by B more than that made by A?
» Explain it
D
Since B computes actual profit on S.P., actual profit for B = 25% of 1000 = Rs. 250 
 
Since A computes actual profit on C.P., C.P. for A = 1000/1.25 = Rs. 800 
 
∴ Actual profit for A = 25% of 800 = Rs. 200

∴ Required difference = 250 − 200 = Rs. 50 
 
Hence, option D is correct.
 
4
The average expenditure of a worker for 6 months was Rs. 95 and he fell into debt. In the next 4 months by reducing his monthly expenses to Rs. 70 he not only cleared off his debt but also saved Rs. 50. His monthly income is
» Explain it
D
We know,

Average of quantities = sum of all quantities / no. of quantities

The average expenditure of a worker for 6 months was Rs. 95.

So, the total expenditure of the worker for 6 months = Rs. 95 × 6 = Rs. 570

In the next 4 months by reducing his monthly expenses to Rs. 70 he not only cleared off his debt but also saved Rs. 50. So, total expenditure in these 4 months = Rs. 70×4 = Rs. 280

We know, 
Total income – total expenditure = total savings

⇒ Total income = total expenditure + total savings

⇒ Total income = (570 + 280) + 50 = 900

So, the total income in 10 months = Rs. 900

∴   His monthly income = Rs. (900 / 10) = Rs. 90

Hence, option D is correct.
5
The average age of a family of five members is 20 years. If the age of the youngest member is 10 years as of now, what was the average age of the family just a day before the birth of the youngest member? Assume that no other members have been added to or removed from this family in this period?
» Explain it
B
At present, total age of the family = 5 × 20 = 100 years
 
Since the youngest member is currently 10 years old, one day before the birth of the youngest member means 10 years ago.
 
∴ Total age of the family one day before the birth of the youngest member = [100 − (10 × 5)] = 50

Now, we must consider only 4 members since the youngest one isn't born yet (at this point of time)
 
∴ Required average age = 50/4 = 12.5 years

Hence, option B is correct.
