Question

• Guess how many children of your weight will be equal to the weight of an elephant of 5000 kg.
• At birth, a baby elephant weighs around 90 kg. How much did you weigh when you were born? Find out. How many times is a baby elephant heavier than you were at birth?
• If a grown up elephant eats 136 kg of food in a day then it will eat around _________ kg in a month.
Guess about how much it will eat in a year.

Answer 1

• Weight of a child of my age = 30 kg
Weight of an elephant = 5000 kg
Total number of children weighing 5000 kg = $\frac{5000}{30}$
= 167 (approximately)

• Weight of a baby elephant = 90 kg
My weight at birth = 3 kg
Number of times a baby elephant was heavier than me at birth = $\frac{90}{3}$
= 30
So, the baby elephant was 30 times heavier than me at birth.

• Food eaten by a grown up elephant in 1 day = 136 kg
Food eaten by a grown up elephant in 30 days = 30 $\times$ 136
= 4080 kg

In a year, it will eat around 50,000 kg of food.
