1500, what is the cost of 6 litres of oil?
​

Answer 1

Cost of 10 litres of oil=₹1500

$cost \: of \: 1 \: litre \: of \: oil =( \frac{1500}{10} )$

Cost of 1 litre of oil=₹150

Cost of 6 litres of oil=₹(150×6)=₹900

Cost of 6 litres of oil is ₹900

Answer 2

We know that-
Cost of 10 litres = ₹1500
So-
We will first find the cost of 1 litre of oil,
Cost of 1 litre = 1500 divided by 10
= cost of 1 litre =₹ 150
Now, we will multiply the cost of 1 litre of oil (₹150) will 6 litres.
Cost of 1 litre = ₹150
Cost of 6 litres = ₹150 multiplied by 6 = ₹900
Hence, cost of 6 litres = ₹900
