Question

$\text{Arun bought 2 kgs of apples, out of}$ $\text{which}\frac{3}{10}\text{kg}$ $\text{were rotten.}$
$\text{Fresh apples left =}$ $\text{grams}$

• A. 1200
• B. 1400
• C. 1300
• D. 1500

Answer 1

The correct option is B 1400

$\text{Total amount of apples bought by}$ $\text{Arun = 2 kg}$

$\text{Amount of rotten apples =}\frac{3}{10}kg$

$\text{First of all, we will have to convert}$ $\text{kilograms to grams.}$

$\text{We know that,}$
$\text{1 kilogram =}$ $\text{1,000 grams}$


$\text{Hence, we will multiply 2 with 1,000.}$

$\text{So, 2 kg}=2\times 1\text{kg}$
$=2\times 1000\text{g}$
$=2,000\text{g}$

$\text{Now, let's calculate the amount of}$ $\text{rotten apples in grams.}$

$\text{So we will multiply}\frac{3}{10}\text{with 2,000.}$

$\frac{3}{10}\text{kg =}$ $\frac{3}{10}$ $\times$ $\text{2 kg}$

$=$ $\frac{3}{10}$ $\times$ $\text{2000 g}$

$=600\text{g}$

$\text{Hence, out of 2,000 g of apples,}$ $\text{600 g were rotten.}$

$\text{Amount of fresh apples}$ $\text{= Total apples - Rotten apples}$


$\text{Thus, 1,400 g of fresh apples}$ $\text{are left.}$
