Question

Find the value of the expression 0.0792+0.252+3.3720.00792+0.0252+0.3372 \frac{0.079^2 + 0.25^2 + 3.37^2}{0.0079^2 + 0.025^2 + 0.337^2}​​

A.

0.3699

B.

3.699

C.

100

D.

10000

Correct option is C

Given:
Expression: 0.0792+0.252+3.3720.00792+0.0252+0.3372 \frac{0.079^2 + 0.25^2 + 3.37^2}{0.0079^2 + 0.025^2 + 0.337^2}​​
Formula Used:
(x10)2=x2100(\frac{x}{10})^2 = \frac{x^2}{100}​​
Solution:
Observe the decimal relationship between the numerator and denominator terms:
0.0079 = 0.07910\frac{0.079}{10}​​

0.025 = 0.2510 \frac{0.25}{10}

0.337 = 3.3710\frac{3.37}{10}​​
Substitute these fractional equivalents into the denominator:
Denominator = (0.07910)2+(0.2510)2+(3.3710)2(\frac{0.079}{10})^2 + (\frac{0.25}{10})^2 + (\frac{3.37}{10})^2​​
Factor out the common multiplier:
Denominator = 1100×(0.0792+0.252+3.372)\frac{1}{100} × (0.079^2 + 0.25^2 + 3.37^2)​​
Now, substitute the simplified denominator back into the original expression:
0.0792+0.252+3.3721100×(0.0792+0.252+3.372)\frac{0.079^2 + 0.25^2 + 3.37^2}{\frac{1}{100} × (0.079^2 + 0.25^2 + 3.37^2)}​​
Cancel the identical bracketed terms in the numerator and denominator:
11100=100\frac{1}{\frac{1}{100}} = 100​​
Final Answer
So the correct answer is (c)
