Question

The values of A and B are:

• A. A = 2.8; B = 8
• B. A = 3.8; B = 5
• C. A = 2.8; B = 4

Answer 1

The correct option is A A = 2.8; B = 8

To find the correct values of A and B, we substitute the given values in the options into the equation A $÷$ B = 0.35.

For first option:
Value of A = 2.8
Value of B = 4

∴ A $÷$ B = 2.8 $÷$ 4
= 2.80 $÷$ 4

Calculating 2.80 $÷$ 4 using the standard method, we get:


So, 2.8 $÷$ 4 = 0.7

But, we know, 0.7 $\ne$ 0.35

So, the first option does not show the correct values of A and B.

Next, for second option:
Value of A = 2.8
Value of B = 8

∴ A $÷$ B = 2.8 $÷$ 8
= 2.80 $÷$ 8

Calculating 2.80 $÷$ 8 using the standard method, we get:


So, 2.8 $÷$ 8 = 0.35

This matches exactly with the values in the given equation.

Now, for the third option:
Value of A = 3.8
Value of B = 5

∴ A $÷$ B = 3.8 $÷$ 5
= 3.80 $÷$ 5

Calculating 3.80 $÷$ 5 using the standard method, we get:


So, 3.80 $÷$ 5 = 0.76

But, we know, 0.76 $\ne$ 0.35

So, the third option does not show the correct values of A and B.

Hence, the correct values of A and B are: A = 2.8; B = 8
