Explanation & Solution

Correct Answer: (C) 141

To find the least number which leaves a remainder of 3 when divided by 12, 16, 24, and 36, we first calculate the Least Common Multiple (LCM) of these divisors. The LCM of 12, 16, 24, and 36 is 144. Adding the required remainder of 3 to the LCM gives 144 + 3 = 141.

सही उत्तर: (C) 141

वह सबसे छोटी संख्या ज्ञात करने के लिए जिसे 12, 16, 24 तथा 36 से विभाजित करने पर 3 शेष बचे, सर्वप्रथम इन भाजकों का लघुत्तम समापवर्त्य (LCM) ज्ञात करना होगा। 12, 16, 24 तथा 36 का LCM 144 है, और इसमें शेष 3 जोड़ने पर 144 + 3 = 141 प्राप्त होता है।
