Question Hard Mathematics Real Numbers 4: HCF and LCM using prime factorisation Class 10 Level 12

चार संकेत दीपक क्रमशः (12), (18), (27) और (36) सेकंड के अंतराल पर चमकते हैं। वे अभी साथ चमके हैं। वे फिर कितने सेकंड बाद साथ चमकेंगे?

Four signal lights flash at intervals of (12), (18), (27), and (36) seconds. They flash together now. After how many seconds will they flash together again?

Explanation opens after your attempt
Correct Answer

A. (108)

Step 1

Concept

The next common flashing time is the LCM of all intervals.

Step 2

Why this answer is correct

\(12=2^2\times3\), \(18=2\times3^2\), \(27=3^3\), and \(36=2^2\times3^2\), so LCM \(=2^2\times3^3=108\).

Step 3

Exam Tip

Use LCM for repeated-time situations. चरण 1: साथ में दोबारा होने वाला समय सभी अंतरालों का लघुत्तम समापवर्त्य होता है। चरण 2: \(12=2^2\times3\), \(18=2\times3^2\), \(27=3^3\), \(36=2^2\times3^2\), इसलिए लघुत्तम समापवर्त्य \(2^2\times3^3=108\) है। चरण 3: समय के दोहराव में लघुत्तम समापवर्त्य का उपयोग करें।

Question Easy Mathematics Real Numbers 4: HCF and LCM using prime factorisation Class 10 Level 10

तीन लाइटें (10), (15) और (20) सेकंड के अंतराल पर चमकती हैं। वे फिर कितने सेकंड बाद साथ चमकेंगी?

Three lights flash at intervals of (10), (15), and (20) seconds. After how many seconds will they flash together again?

Explanation opens after your attempt
Correct Answer

B. (60)

Step 1

Concept

The next common flashing time is the LCM of (10), (15), and (20).

Step 2

Why this answer is correct

\(10=2\times5\), \(15=3\times5\), \(20=2^2\times5\).

Step 3

Exam Tip

\(2^2\times3\times5=60\), so the answer is (60) seconds. चरण 1: साथ चमकने का अगला समय (10), (15) और (20) का लघुत्तम समापवर्त्य है। चरण 2: \(10=2\times5\), \(15=3\times5\), \(20=2^2\times5\)। चरण 3: \(2^2\times3\times5=60\), इसलिए उत्तर (60) सेकंड है।
