Question

The weight of a baby elephant was 218.99 kg. After two years, his weight increased by 109.85 kg. Find the weight of an elephant after two years?

Answer 1

Hint: We have given the initial weight of a baby elephant which was 218.99 kg and after two years its weight increased by 109.85 kg. So, the new weight of the baby elephant after two years is calculated by adding 218.99 kg to 109.85 kg. The result of this addition is the weight of the elephant after two years.

Complete step-by-step solution:
The weight of a baby elephant is given as 218.99 kg. And after two years, the baby has gained a weight of 109.85 kg and we are asked to find the weight of the elephant after two years.
We are going to find the weight of the baby elephant after two years by adding its initial weight of 218.99 kg into the increased weight which is 109.85 kg.
Now, adding 218.99 kg to 109.85 kg we get,
$\begin{align}
  & \text{ }218.99kg \\
 & +109.85kg\\
 &\overline{328.84kg} \\
\end{align}$
From the above calculations, we got the addition of the initial weight into the increased weight as 328.84 kg.
Hence, the weight of a baby elephant after two years is equal to 328.84 kg.

Note: You can check the weight of the baby elephant that you are getting after two years is by subtracting the increased amount of weight from the new weight.
The new weight that we have solved above is 328.84 kg and the increased weight in the period of 2 years is 109.85 kg.
Subtracting 109.85 kg from 328.84 kg we get,
$\begin{align}
  & \text{ }328.84kg \\
 & \dfrac{-109.85kg}{218.99kg} \\
\end{align}$
Hence, the weight we are getting from the above subtraction is the initial weight of the baby elephant. So, the weight which we have calculated in the above solution after two years is the correct weight.
