Question

A vendor supplies $42litres$ of milk to a hotel in the morning and $58litres$ of milk in the evening. If the milk costs ₹ $30$ per litre, how much money is due to the vendor per day?

Answer 1

Step I - A vendor supplies milk to the hotel in the morning = $42litres$

A vendor supplies milk to the hotel in the evening = $58litres$

Cost of milk per litre = ₹ $30$

So, total money is due to the vendor per day = $42\times 30+58\times 30$

Step II - Taking $30$ as common from the above numbers.

$42\times 30+58\times 30$ = $30\times (42+58)$

= $30\times 100$ = $3000$

Hence, total money is due to the vendor per day = ₹$3000$.
