Question

A pond in a field holds 120000 litres of water. It costs 18000 rupees to make such a pond. How many ponds will be required to store 480000 litres of water, and what would be the expense?​

Answer 1

Answer:

it would take 4 ponds and the money required to do it is 72000

Answer 2

Answer:

The answer is 72000 because

Number of ponds required to store 120000 litres of water =1

Number of ponds required to store 1 litre of water = 1/120000

Number of ponds required to store 480000 litres of water = 1/120000 × 480000 = 4

Thus, 4 ponds required to store 480000 litres of water

Now, cost of making 1 pond = RS 18000

Cost of making 4 ponds

= 18000 rupees × 4 = 72000 rupees.

Then the answer is 72000
