- Question-1
- Explanation

a) 8.3 b) 24 c) 12 d) 6.6

**Answer: a)**8.3 days

Total amount of work W = N* D*W

Where N = Number of men, D = Number of days, W = amount of work per day.

Applying the above formula for company A we get, work done by company A to deliver

100 parcels = 5*5 *8 = 200 –eq 1 Work done by company B to deliver 100 parcels = 5*D *6 = 24D –Seq2

Since the work to be done is same in both the cases, eq1 = eq2 or 200 = 24D or D= 8.3

- Question-2
- Explanation

2. Consider a group of working men. If 1/10^{th} of the workers are absent then work of each person would be increased by.

a) 20% b) 22.22% c)10% d) 11.11%

**Answer: d) 11.11%**

Let us assume 100 units of work is divided among 10 men.

When no one is absent, each member have to do 100/10 = 10 units of the work

With 1/10^{th} of men absent, there would be 9 men present.

Now, if 100 units of work is to be done by the 9 men present, each should do 100 / 9 units of work.

Extra work required from each member when only 9 men are present = 100 /9 – 10 = 10 /9 units.

Percentage of increase of work for each member = ( Extra Work required from each member when only 9 men are present) / ( Original amount of work when everyone is present) * 100 % = ()10/9)*/10)* 100% = 11.11%

- Question-3
- Explanation

3) In an examination, it is required to score 32% of the aggregate marks for a student to pass the examination. Raju has scored 250 marks and was declared failed by 22 marks. Find the aggregate marks?

a) 720 b) 750 c) 800 d) 850

**Answer: d) 850**

Let the aggregate marks be X. Minimum pass mark is = 250 + 22 = 272

32% of X is 272. i.e. (32/100)* X = 272

X = 272 * 100 /32 = 850. Hence the aggregate mark is 850.

- Question-4
- Explanation

An Individual deposited 20% of 25% of 30% of what he had into his account with a bank. If he deposited Rs.750, how much was he having initially with him before depositing?

a) Rs.500000 b) Rs.50,000 c) Rs.5000 d) Rs.15000

**Answer: b) Rs. 50,000**

Let the initial amount he had be A

30% of A = 30/100*A

25% of 30% of A = 25/100 *30/100 * A

20% of 25% of 30% of A = 20/100 * 25/100 *30/100 * A

But it is given that 20% of 25% of 30% of A = 750

Or 20/100 * 25/100 * 30/100 * A = 750

Therefore A = 750 * 100/20* 100/25 * 100/30 = 50000

- Question-5
- Explanation

The Population of a Village is 45000. 5/9^{th} of them are males and rest females. If 40% of the males are married, then the percentage of married females is:

a) 50 b) 40 c) 70 d) 60

**Answer: a) 50**

Total Population – 45000.

Out of this 5/9 are males – 25000

Out of males 40% are married – 10000

Number of female – 20000. Number of Female married, which should be equal to that of married males – 10000

Percentage of married female – (10000/20000) * 100 = 50%.
