Question

a cheater manipulated his wighing machine so that it show 1kg for 970grams .how much profit does he get?​

Answer 1

Answer:

By manipulating his weighing machine a cheater can get a profit of 30grams/kg.

Explanation:

Given:
The original weight = 1kg =1000grams

Weight after manipulation = 970grams

To find: Profit=?

We can find the profit by subtracting the weight after manipulation from the original weight.

∴ Profit = 1000-970=30grams

Thus, by manipulating his weighing machine a cheater can get a profit of 30grams/kg.

Answer 2

Answer:

The cheater gets a profit of 30 grams per kg by manipulating his machine.

Explanation:

Given: The original weight measured by the machine is 1Kg = 1000 grams

As the machine reads 30 grams less per kg, therefore

Weight that is measured after manipulation is 970 grams

We have to find the profit?

For finding the profit we must subtract the weight after manipulation from the original weight

∴  profit =1000-970 = 30 grams

Hence, by manipulating his weighing machine a cheater can get a profit of 30grams/kg.
