If (461 + 462 + 463 + 464) is divisible by ?, then ? =_____________?
Correct answer: D. None of these
- A. 3
- B. 11
- C. 13
- D. None of these
Explanation
The sum is 461 + 462 + 463 + 464 = 1850. It is not divisible by 3 because its digit sum is 14, not by 11 because 11 x 168 = 1848, and not by 13 because 13 x 142 = 1846. Therefore none of the listed divisors works, so option d is correct; option a is the likely choice for students who use only the apparent consecutive-number pattern.

About Ratio and Proportion
Ratios compare quantities in the same units, while proportions state that two ratios are equal. Problems cover simplification, division in a given ratio, direct and inverse variation, scale, and missing terms, with attention to the difference between a ratio and a fraction representing part of a whole.
