Question

In an elephant park, the heaviest elephant Chloe, weighs 5000 kg. The weights of other three elephants are Jane - 3500 kg, Julie - 3200 kg, Kim - 4000 kg. Which elephant weighs seven-tenths of the weight of Chloe?

• A. Kim
• B. Julie
• C. Jane
• D. Insufficient data

Answer 1

The correct option is C Jane

Chloe's weighs = 5000 kg
Jane's weight = 3500 kg
Julie's weight = 3200 kg
Kim's weight = 4000 kg

Elephant which weighs seven-tenths of the weight of Chloe =
$\frac{7}{10}\times 5000=\frac{7}{10}\times \frac{5000}{1}=\frac{7\times 5000}{10}$
$=\frac{7\times 500\times 10}{10}=3500$ kg
Jane's weightis 3500 kg.
$\therefore$ Jane weighs seven-tenths of Chloe's weight.
