• A. $\$$101.75
• B. $\$$101.25
• C. $\$$102.25
• D. $\$$102.75

Answer 1

The correct option is B $\$$101.25

Weight of silver = 3.32 kg
Cost of 3.32 kg of silver = $\$$336.15

∴ Cost of 1 kg of silver
= $\$$(336.15 $÷$ 3.32)

Calculating the value of 336.15 $÷$ 3.32, we get:


Now, we need to calculate the value of 4.15 $÷$ 3.32

We can write 4.15 $÷$ 3.32 as:


∴ 4.15 $÷$ 3.32 = 415 $÷$ 332

Now, 415 = 415.00
So, 415 $÷$ 332 = 415.00 $÷$ 332

Calculating 415.00 $÷$ 332 by standard method, we get:


So, 4.15 $÷$ 3.32 = 1.25

Placing this value in the initial equation, we get:


Hence, the cost of 1 kg of silver is
$\$$101.25.
