Question

A zoo had 5 tigers. The tigers ate 120 kg of meat everyday. If 3 more tigers are adopted by the zoo the following year, how much meat will be required every month?

• A. 196 kg
• B. 192 kg
• C. 160 kg
• D. 172 kg

Answer 1

The correct option is B 192 kg

When the zoo had 5 tigers, 120 kg of meat was required daily. If the number of tigers increases, then the amount of meat required will also increase.

$\therefore$ This is a case of direct proportion. Since 3 more tigers have been adopted by the zoo, the total number of tigers is 3 + 5 = 8.
Using the formula for direct proportion,
$\frac{Numberoftigers}{Quantityofmeatrequired}=constant$
$\Rightarrow \frac{5}{120}=\frac{8}{Quantityofmeatrequired}$
$\therefore Quantityofmeatrequired=\frac{120}{5}\times 8=192kg$.
