Q:

A man invests Rs.5000 for 3 years at 5% p.a. compound interest reckoned yearly. Income tax at the rate of 20% on the interest earned is deducted at the end of each year. Find the amount at the end of the third year

A) Rs.5624.32 B) Rs.5423
C) Rs.5634 D) Rs.5976
 
Answer & Explanation Answer: A) Rs.5624.32

Explanation:

 

 

 

5% is the rate of interest. 20% of the interest amount is paid as tax.

 

i.e  80% of the interest amount stays back.

 

 if we compute the rate of interest as 80% of 5% = 4% p.a., we will get the same value.

  

The interest accrued for 3 years in compound interest = 3 x simple interest on principal + 3 x interest on simple interest + 1 x interest on interest on interest.

 

= 3 x (200) + 3 x (8) + 1 x 0.32 =600 + 24 + 0.32 = 624.32

 

 

 

The amount at the end of 3 years = 5000 + 624.32 = 5624.32

Q:

A group of workers was put on a job. From the second day onwards, one worker was withdrawn each day. The job was finished when the last worker was withdrawn. Had no worker been withdrawn at any stage, the group would have finished the job in 55% of the time. How many workers were there in the group?

A) 50 B) 40
C) 45 D) 10
 
Answer & Explanation Answer: D) 10

Explanation:

Let the number of workers be x.

Now, Using work equivalence method,

X + (X-1) + (X-2)+ . . . . + 1 = X *55% of X

 

=> [X * (X+1)] / 2 = X * (55X/100)    [because, Series is in AP. Sum of AP = {No. of terms (first term+ last term)/2} ]

Therefore, X = 10

Q:

Read the following statements and answer the question given below.

U.S. fraternity and sorority members who drink heavily while in school don’t tend to drink after graduation, according to a recent study in Psychology of Addictive Behaviours.

Which of the following would be a logical extension of the above passage?

A) Most men come out of a drinking binge after they cross thirty. B) With graduation comes a sense of responsibility which makes students abstain from such vices.
C) Drinking begins as a group activity and as students leave these groups, the habit of drinking is also left behind. D) Drinking heavily during college days make most students realize the harmful effects of alcoholic drinks.
 
Answer & Explanation Answer: C) Drinking begins as a group activity and as students leave these groups, the habit of drinking is also left behind.

Explanation:

The passage only provides the information that students drink in school but seem to stop binging after they graduate. Option [A] is incorrect as there is no mention in the passage that students
are only males and that they graduate at thirty. Options [B] and [D] are incorrect because it is not mentioned so in the passage. Since the passage talks about student groups - 'fraternity and sorority members' - a logical extension would be that it is these groups that prod students to begin drinking and with the breaking of these groups, the habit is also broken. Hence, [C].
