The L.C.M of two numbers is 48. The numbers are in the ratio 2:3. The sum of numbers is__________?

Correct answer: C. 40

  • A. 28
  • B. 32
  • C. 40
  • D. 64Islamic Studies Quiz

Explanation

Let the numbers be 2x and 3x. Their LCM is 6x, so 6x = 48 gives x = 8; the sum is 2 x 8 + 3 x 8 = 40. The likely mistake is choosing 32, which results from failing to add both ratio parts after finding the scale factor.

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.
