The ratio of two numbers is 3:4 and their LCM is 120. What is the sum of the two numbers?
70
140
35
105
Answer: A
Solution
Let the numbers be 3x and 4x. Their LCM = 12x = 120, so x = 10. Sum = 3x + 4x = 7 × 10 = 70.
दो संख्याओं का अनुपात 3:4 है और उनका लघुत्तम समापवर्त्य 120 है। दोनों संख्याओं का योग क्या है?
70
140
35
105
उत्तर: A
हल
मान लें संख्याएँ 3x और 4x हैं। उनका लघुत्तम समापवर्त्य = 12x = 120, इसलिए x = 10। योग = 3x + 4x = 7 × 10 = 70।
