Question

24% of weight of an explosive mixture is saltpetre. Find the weight of a sample in which the other ingredients weigh 9.12 gram.​

Answer 1

Answer:

weight of the sample is 12 gram.

Step-by-step explanation:

Here it is given that 24% of weight in the explosive mixture is saltpetre.

Therefore other perticles weight (100-24) % = 76%

Now it is given that other perticles weight 9.12 gram.

Let the weight of the total mixture be X.

Therefore,

76% of X= 9.12.

X =( 9.12/76) ×100

X= 12 gram.

Therefore weight of the sample is 12 gram.
