Question

Find the value of B from the following statements:

• A. B = 6.24
• B. B = 6.12
• C. B = 5.24
• D. B = 5.12

Answer 1

The correct option is D B = 5.12

The given statements are:


From Statement 1, we get:
12.25 $\times$ A = 250.88
⇒ A = 250.88 $÷$ 12.25

Rewriting 250.88 $÷$12.25, we get:


So, 250.88 $÷$ 12.25 = 25088 $÷$ 1225

Calculating 25088 $÷$ 1225 by standard algorithm method, we get:


∴ A = 20.48

Now, Statement 2 states:


So,
A = 4 $\times$ B
⇒ B = A $÷$ 4

Now,
A = 20.48
⇒ B = 20.48 $÷$ 4

Calculating 20.48 $÷$ 4 by standard method, we get:


Hence, B = 5.12.
