Which can be measured more accurately : the total amount of fat in cream of tomato soup or the total amount of fat in sweet corn soup? Explain.

Answer 1

Given, the serving size of 1 cup of sweet corn = 240 ml

Also, total fat = 2g on 2%

Now, we know x% of `n = x/100 xx n`

⇒ 2% of fat in sweet corn of 1 cup (with 2 servings per container) = `2/100 xx 240`

= `48/10`

= 4.8 g

⇒ For one serving = `4.8/2` = 2.4 g

Given, serving size of 1 cup of cream of tomato = 240 ml

Also, total fat = 2g on 3%

Now, we know x% of `n = x/100 xx n`

⇒ 3% of fat in cream of tomato of 1 cup (with 2 servings per container) = `3/100 xx 240`

= `72/10`

= 7.2 g

⇒ For one serving = `7.2/2`  = 3.6 g

Hence, sweet corn soup can be compared more accurately.

Since, 2.4 g is nearest to 2 g when compared to 3.6 g to 3 g.
