Question

Jacob has two puppies. He feeds each puppy $100$ grams of food twice every day. If he bought a 6 kg pack of food, how many days will the pack last?

• A. $30$ days
• B. $15$ days
• C. $35$ days
• D. None of the above

Answer 1

The correct option is B $15$ days

Given, Jacob has two puppies and each puppy eats 100 g of food twice everyday.

Amount of food given to each puppy everyday $=100+100=200$ grams.

Total amount of food consumed by puppies in one day $=2\times 200=400$ grams.

Jacob buys $6$ kilograms pack of food.
We know,
$1$ kilogram $=1000$ grams.
$\Rightarrow 6$ kilograms $=6\times 1000=6000$ grams.

Number of days the pack of food will last $=\frac{\text{Total food}}{\text{Food consumed each day}}=\frac{6000}{400}=15\text{days}$.
Hence, food will last for $15$ days.
