Answer: Option B

Explanation:

difference between the numbers are respectively 3,6,7,5,24,25

Now, according to 6-7-5,

7-2=5, two number less than previous one

So, this must be 24-25-23 (25-2=23).

Now, 78+23=101.

3664 . What is the number of divisor of 1008?

A. 12
B. 20
C. 30
D. 32

View Answer	Favorite Question

Answer: Option C

Explanation:

To find the number of divisors of 1008, we can first factorize 1008 into its prime factors and then use the formula for finding the number of divisors.

Prime factorization of 1008: 1008 = 2^4 * 3^2 * 7

Now, to find the number of divisors, we use the following formula:

Number of divisors = (a + 1)(b + 1)(c + 1)...

Where a, b, c, ... are the exponents of the prime factors in the factorization.

In this case: a = 4 (the exponent of 2) b = 2 (the exponent of 3) c = 1 (the exponent of 7)

Number of divisors = (4 + 1)(2 + 1)(1 + 1) = 5 * 3 * 2 = 30

So, the number of divisors of 1008 is 30.

3665 . What is the number of integers between 101 and 199 which are exactly divisible by 5 or 7?

A. 30
B. 29
C. 32
D. 31

View Answer	Favorite Question

Answer: Option A

Explanation:

LCM of 5 and 7 is 35

No. of integer between 101 and 199 devided by 35 is 3

No.of integer between 101 and 199 devided by 5 is 19

No of integer between 101 and 199 devided by 7 is 14

so, No.of integer between 101 and 199 divided by 5 or 7 are = 19 + 14 - 3 = 30

3666 . What is the number of integers between 101 and 199 which exactly divisible by 5 or 7?

A. 31
B. 30
C. 32
D. 35
E. None of them

View Answer	Favorite Question

Answer: Option A

Explanation:

In 5 years, capital will be 200 tk

so, the interest = (200 - 100) = 100tk

we know, i = pnr

or, r = i/pn

or, r = 100/(100*5)

∴r = 1/5

the rae of simple interest = 1/5 * 100% = 20%

ans: 20%
