1.

A printer numbers the pages of a book starting with 1 and uses 3189 digits in all. How many pages does the book have ?

A.

1000

B.

1074

C.

1075

D.

1080

View answer & explanation

Correct answer is B

No. of digits in 1-digit page nos. = 1x9 = 9.

No. of digits in 2-digit page nos. = 2 x 90 = 180.

No. of digits in 3-digit page nos. = 3 x 900 = 2700.

No. of digits in 4-digit page nos. = 3189 - (9 + 180 + 2700) = 3189 - 2889 = 300.

Therefore No. of pages with 4-digit page nos. = (300/4) = 75.

Hence, total number of pages = (999 + 75) = 1074.

Edet's age was equal to square of some number last year and the following year it would be cube of a number. If again Edet's age has to be equal to the cube of some number, then for how long will he have to wait?

A.

10 years

B.

38 years

C.

39 years

D.

64 years

View answer & explanation

Correct answer is B

Clearly, we have to first find two numbers whose difference is 2 and of which the smaller one is a perfect square and the bigger one a perfect cube.

Such numbers are 25 and 27.

Thus, Edet is now 26 years old. Since the next perfect cube after 27 is 64,

so required time period = (64 - 26) years = 38 years.

5.

An enterprising businessman earns an income of $1 on the first day of his business. On every subsequent day, he earns an income which is just double of that made on the previous day. One the 10th day of business, his income is

A.

$29

B.

$210

C.

$10

D.

$102

View answer & explanation

Correct answer is A

Income on the first day = $1

Income on the 2nd day = $(1x2) = $21

Income on the 3rd day = $(21 x 2) = $22 and so on. Thus, Income on the nth day = $2n-1.

Therefore Income on the 10th day = $29.
