Question

The cost of 15 packets of biscuits ,each weighing 750 grams,is rs.300. what will be the approximate cost of 25 packets ,if each packets weighs 1 kg

Answer 1

The weight of one packet of biscuit = 750 grams

So, the weight of 15 packets of biscuits = $750 \times 15$ = 11,250 grams.

The cost of biscuits with weight of 11,250 grams = Rs 300

So, the cost of biscuit with weight of 1 gram = $300 \div 11,250$

= Re $\frac{2}{75}$

Now, we have to determine the cost of 25 packets of biscuits with weight 1 kg

The weight of one packet of biscuit  = 1000 grams

So, the weight of 25 packets of biscuits = 25,000 grams

Since, the cost of biscuit with weight of 1 gram =  Re $\frac{2}{75}$

So, the cost of biscuits with weight 25,000 grams = Rs $\frac{2}{75} \times 25,000$

= Rs 667

Therefore, the cost of 256 packets of biscuits with each packet weight as 1 kg is Rs 667.

= Rs 667
