Question

Raj is making korma for a party. He puts 25 g of curry powder on a food scale. The food scale has marks every 0.1 g. To measure fo each recipe, Raj removes 1/4 g of curry powder from the scale 7 times. He says the mass of the remaining curry powder is between 18.2 g and 18.3 g.is Raj right?

Answer 1

He put 7G of curry powder on a food scale.

If he removes 1/4 seven times, then we can find the remaining curry powder using the next operation:

7(1/4) = 7/4

Then

25G - 7/4 = 23.25

Therefore, Raj is not right because 7 X 1/4= 7/4 and 25 - 7/4 = 23.25, which is between 23.2 g and 23.3 g.
