Answer 1

Answer:

Hey mate ✨

Here are your answers

1. (b) 1'x28

2. (c) 4

3. You didn't give a proper option here

actually the answer is 8000

4. (a) Both A and B are true

Thank you

Refer explanation for more clarification

Step-by-step explanation:

Here is the explanation for each

1. The standard form of 28 is 1'x28 because 1' is 1

then 1*28 is 28

So....it's (b)

2. Divisors are nothing but the factors

The factors of 14 are 1,2,7,14

So ...there are 4 divisors

Therefore

The answer is (c) i.e., 4 (it's given at the top)

3. Here is the thing ...

Actually...the divisors of 20 are 1,2,4,5,10,20

The product of these is

1*2*4*5*10*20 = 2*4*5*10*20

= 8*5*10*20

= 40*10*20

= 400*20

= 8000

So the answer is 8000

But here there is no such option given

Therefore

Insufficient data

4. Statement A is true because a prime factor have only 2 factors ...1 and the number itself

Statement B is true because the sum is 1+the number itself

i.e., the sum is one more than it

So ...both the statements are true

therefore

The answer is (a) Both A and B are true
