Question

In a firm, there are two manufacturers - Vicky and Noah. Vicky has $11$ machines, which are capable to produce $550$ finished goods in a day. Whereas, Noah has $18$ machines, which produce $720$ finished goods per day. Which manufacturer has more efficient machines?

• A. Machines of Vicky are more efficient.
• B. Machines of Noah are more efficient.
• C. Machines of both Vicky and Noah are equally efficient.
• D. Cannot be determined

Answer 1

The correct option is A Machines of Vicky are more efficient.

Tabular representation of the provided data is as follows:
Record of Finished Goods Production

Manufacturers	No. of Machines	No. of Finished Goods/day
Vicky	$11$	$550$
Noah	$18$	$720$

To determine how efficiently each manufacturer's machines perform, we need to calculate the number of finished goods produced by each machine per day for both Vicky and Noah.

$\underset{–}{\text{For manufacturer Vicky}}$
$\text{Average number of goods produced per day}=\frac{\text{Number of finished goods}}{\text{Number of machines}}$
$\Rightarrow \text{Average number of goods produced per day}=\frac{550}{11}$
$\Rightarrow \text{Average number of goods produced per day}=50$

$\underset{–}{\text{For manufacturer Noah}}$
$\text{Average number of goods produced per day}=\frac{\text{Number of finished goods}}{\text{Number of machines}}$
$\Rightarrow \text{Average number of goods produced per day}=\frac{720}{18}$
$\Rightarrow \text{Average number of goods produced per day}=40$

As the average number of finished goods produced per day by Vicky's machines is more, the machines of Vicky are more efficient in comparison to Noah's machines.
