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 everyday?
  1. 196 kg
  2. 192 kg
  3. 160 kg
  4. 172 kg


Solution

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.
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,
Number of tigersQuantity of meat required = constant
5120 = 8Quantity of meat required
 Quantity of meat required = 1205×8=192 kg.
