Refer to the following number series and answer the question that follows (all numbers are single digit numbers only). Counting to be done from left to right only.

(Left) 3 2 4 9 1 8 7 6 3 2 1 5 6 4 7 8 3 9 4 6 5 7 4 1 5 7 2 (Right)

How many such even digits are there each of which is immediately preceded by a perfect square and immediately followed by an odd digit? (NOTE: 1 is also a perfect square.)

This question is based on the five, three-digit numbers given below.

(Left) 482 254 371 273 463 (Right)

(Example- 697 – First digit = 6, second digit = 9 and third digit = 7) (NOTE: All operations to be done from left to right.)

What will be the resultant if the third digit of the highest number is added to the second digit of the lowest number?

Three statements are given, followed by three conclusions numbered I, II,and III. Assuming the statements to be true, even if they seem to be at variance with commonly known facts, decide which of the conclusions logically follow(s) from the statements.

Statements:

All phones are tablets.

No tablet is a calculator.

All drives are calculators.

Conclusions:

I. Some drives are phones.

II. Some calculators are phones.

III. No tablet is a drive.

A statement is given followed by two arguments I and II. Read the statement and the arguments carefully and select the appropriate answer from the given options.

Statement:

In spite of all apartments having the same square foot area, rents of the apartments above the 6th floor are higher in most high-rise apartment buildings.

Arguments:

I. It is riskier to live on higher floors, since the dependence on lifts is much more critical than the lower floors which can be accessed by stairs.

II. Air pollution is several times lower on higher floors than on the lower floors.

This question is based on the five, three-digit numbers given below.

(Left) 325 846 483 215 468 (Right)

(Example- 697 – First digit = 6, second digit = 9 and third digit = 7) NOTE - All operations to be done from left to right.

What will be the resultant if the second digit of the highest number is added to the second digit of the lowest number?
