Question

the cost of 16 bags of washing powders each weighing 1.5kg is rupees672. find the cost of 18 bags of the same each weighing 2kg ?

Answer 1

Mass of 1 bag = 1.5 kg
Mass of 16 bags = 16 × 1.5 kg = 24 kg

Cost of 24 kg powder is ₹672
Cost of 1 kg powder = ₹672 / 24 = ₹28

Now,
Mass of 1 bag = 2 kg
Mass of 18 such bags = 18 × 2 kg = 36 kg

Cost of 36 kg powder = 36 kg × ₹28 per kg = ₹1008

Cost of 18 bags each weighing 2 kg is ₹1008

Answer 2

Answer:

1008/-

Step-by-step explanation:

16 x 1.5 = 24

24/2 = 12

So, 12 two kg bags, make 672/-

using direct proportion, 672/12 = x/18

= 672/12 x 18 = x

= 1008 = x

x = 1008
