Question

If weight of $1$ mango is $250$ gms, then calculate the weight of $16$ mangoes. (Write your answer in kilograms)

• A. $1$
• B. $2$
• C. $3$
• D. $4$

Answer 1

The correct option is D $4$

Weight of $1$ mango $=250$ $\text{gram}$

Weight of $16$ mangoes $=250\times 16\text{gram}=4000$ $\text{gram}$

We know that

$1$ $\text{kg}=1000$ $\text{gram}$

$1$ $\text{gram}=\frac{1}{1000}$ $\text{kg}$

We have to convert $4000$ $\text{gram}$ to $\text{kg}$:

$4000$ $\text{gm}=\frac{1}{1000}\times 4000$ $\text{kg}$

$=\frac{4000}{1000}$ $\text{kg}$

$=4$ $\text{kg}$

So, option $D$ is correct.
