Question

The cost of 16 packets of salt, each weighing 900 grams is Rs. 28. What will be the cost of 27 packets, if each packet weighs 1 kg?

Rs. 52.50
Rs. 56
Rs. 58.50
Rs. 64.75

Answer 1

heya!

here's ur answer...

Let the required cost be ₹x.

Then,More packets, More cost (Direct Proportion)

More weight, More cost (Direct Proportion)

Packets 16 : 27

Weight 900 : 1000 :: 28 : x

(16 x 900 x x) = (27 x 1000 x 28)

x = (27 x 1000 x 28) /16 x 900

= 105 /2

= 52.50

hope this helps...

Answer 2

The cost of 27 packets of 1 kg each is Rs. 52.50(option a).

Step-by-step explanation:

• The weight of each packet $=900 g$  

• The weight of 16 such packets $= 16\times 900 = 14400 g = 14.4 kg$  

• Cost of 14.40 g of salt $= Rs 28$

• Thus, the cost of 1 kg salt $= Rs (\frac{28}{14.40}) = Rs 1.944$

Now, to find the cost of 27 packets of 1 kg

Total weight$= 27 \times 1 = 27 kg$

• So, cost $= 27 \times Rs 1.944 = Rs 52.50$

The cost of 27 packets is Rs. 52.50.
