What will come in the place of the question mark '?' in the following question?

[tex]\[ 17 \frac{1}{3} + 21 \frac{1}{2} = 33 \frac{1}{3} \% \text{ of } ? \][/tex]

1. 201.5
2. 108.4
3. 116.5
4. 118.9
5. 115.3



Answer :

To solve this problem, we need to determine what number the given percentage represents.

We're given:
[tex]\[ 17 \frac{1}{3} + 21 \frac{1}{2} = 33 \frac{1}{3}\% \text{ of } ? \][/tex]

Let's break this down step-by-step:

1. Convert the mixed numbers to improper fractions or decimals:
[tex]\[ 17 \frac{1}{3} = 17 + \frac{1}{3} \approx 17.3333 \][/tex]
[tex]\[ 21 \frac{1}{2} = 21 + \frac{1}{2} = 21.5 \][/tex]

2. Add these two values together:
[tex]\[ 17.3333 + 21.5 = 38.8333 \][/tex]

3. Convert the percentage [tex]\( 33 \frac{1}{3}\% \)[/tex] to a decimal:
[tex]\[ 33 \frac{1}{3}\% = 33.3333\% = \frac{33.3333}{100} \approx 0.3333 \][/tex]

4. Set up the equation to find the unknown number [tex]\( x \)[/tex]:
[tex]\[ 38.8333 = 0.3333 \times x \][/tex]

5. Solve for [tex]\( x \)[/tex]:
[tex]\[ x = \frac{38.8333}{0.3333} \approx 116.5 \][/tex]

Therefore, the number that satisfies the equation is approximately [tex]\( 116.5 \)[/tex].

So, the correct answer is:
[tex]\[ \boxed{116.5} \][/tex]
