The sum of two number is twice the difference between two number.if the one number is 10 find the second number ?

Answer : 30

Explanation:

Assuming the second number is x
10 + x = 2*(x-10)
Simplify and solve
10 + x = 2x-20
10+20= x
x = 30
Therefore the second number is 30

The pulse rate of a person is 15 beats in 10 seconds. At this rate, what will be pulse rate of the person per minute?

A. Data insufficient

B. 100 beats per minute

C. 90 beats per minute

D. 150 beats per minute

Answer : C. 90 beats per minute

Explanation:

A person pulse rate in 10 seconds = 15.
A person pulse rate of one second 15/10 = 1.5.
A person pulse rate at one minute is 60 * 1.5 = 90.
A person pulse rate is 90 beats per minute.

How many factors does the number 2,876 have ?

A. 8

B. 7

C. 6

D. 5

Answer : C. 6

Explanation:

Take the power of terms as a and b.
Using the equation for determining the number of factors, d(n) = (a+1) (b+1)
2876 = 22 * 7191
D (2876) = (2+1) (1+1) = 6
So, answer is 6

Factors of 2876 = 1, 2, 4, 719, 1438, 2876

Consider the following quotients :
1) 368.39 divided by 17
2) 170.50 divided by 62
3) 875.65 divided by 83
Their correct sequence in decreasing order is :

A. 1, 3, 2

B. 2, 1, 3

C. 2, 3, 1

D. 3, 1, 2

Answer : A. 1, 3, 2

Explanation :

  • 36839/17 = 2167, Dividend contains 2 places of decimal.
    So, 368.39 / 17 = 21.67
  • 17050/62 = 275, Dividend contains 2 places of decimal.
    So, 70.50/62 = 2.75
  • 87565/83 = 1055, Dividend contains 2 places of decimal.
    So, 875.65/83 = 10.55

Since 21.67 > 10.55 > 2.75. The desired order is 1, 3, 2.

X is a 5 digit number when we subtract the sum of the digits form X, it becomes divisible by _____ ?

A. 5

B. 1

C. 9

D. 6

Answer : C. 9

Explanation:

Every multiple of 9 (9, 18, 27, 36, etc.) has the property that its digits will always add up to a multiple of 9.
For example, the number 4,968 is a multiple of 9 (552 × 9), and its digits add up to 27 (3 × 9).
Because of how the problem is stated, with four-digit numbers, the sum of the digits will always be 9 or 18 or 27.
Adding 1 + 8 or adding 2 + 7 (as specified in the problem) again gives 9.

A. 23

B. 24

C. 25

D. 26

Answer : B. 24

Explanation:

Numbers less than 100 divisible by 2 are 10, 12, 14, 16,…,98.
Total numbers divisible by 2 are 45
Remaining numbers are 11, 13, 15, 17, 19…99 = 45

Numbers divisible by 3 in the above numbers are 15, 21, 27, 33, 39, 45, 51, 57, 63, 69, 75, 81, 87, 93 and 99.
Total numbers divisible by 3 are = 15
Remaining integers = 45-15 = 30.

Numbers divisible by 5 in the remaining numbers = 25, 35, 55, 65, 85, 95
Total numbers = 6
Remaining 30-6 = 24.

So 24 numbers are not divisible by 2, 3 and 5.

If the number 7×86038 is exactly divisible by 11, then the smallest whole number in place of x ?

A. 1

B. 2

C. 3

D. 4

Answer : C. 3

Explanation:

The given number = 7×86038
Sum of the odd places = 8 + 0 + 8 + 7 = 23
Sum of the even places = 3 + 6 + x
(Sum of the odd places) – (Sum of even places) = Number (exactly divisible by 11)
23 – (9 + x) = divisible by 11
14 – x = divisible by 11.
X must be 3, to make given number divisible by 11.

A. 4

B. 5

C. 6

D. 7

Answer : B. 5

Explanation:

When the integer n is divided by 8, the remainder is 3. What is the remainder if 6n is divided by 8 ?

A. 0

B. 2

C. 1

D. 3

Answer : B. 2

Explanation:

When n is divided by 8, the remainder is 3 may be written as
n = 8 k + 3
Multiply all terms by 6
6 n = 6(8 k + 3) = 8(6k) + 18
Write 18 as 16 + 2 since 16 = 8 * 2.
= 8(6k) + 16 + 2
Factor 8 out.
= 8(6k + 2) + 2
The above indicates that if 6n is divided by 8, the remainder is 2. The answer is B.

It can be written as x $ y + z
2012 – 0 + 2012 – 1912 = 2112

The remainder when m + n is divided by 12 is 8, and the remainder when m – n is divided by 12 is 6. If m > n, then what is the remainder when mn divided by 6 ?

A. 3

B. 4

C. 2

D. 1

Answer : D. 1

Explanation:

(m+n)/12 remainder is 8 so m + n = 8 + 12 = 20
(m-n)/12 remainder is 6 so m – n = 6 + 12 = 18
Solving this m = 19,n = 1
( m * n ) / 6 = ( 19 * 1 ) / 6 remainder is 1.

What is the remainder when (1234567890123456789)24 is divided by 6561 ?

A. 7

B. 5

C. 3

D. 0

Answer : D. 0

Explanation:

The digital sum of number is (1+2+3+4+5+6+7+8+9+0+1+2+3+4+5+6+7+8+9) = 90 = (9+0) = 9 So it is divisible by 3 or 9
The given divisor 6561 = 94
So 924/94 Reminder is 0.
