Total expenditure = Rs. 20,000
Expenditure on education = 26% of total expenditure
= $\frac{26}{100}$ × 20000
= Rs. 5,200

Question : What is the LCM of 0.15, 0.18, and 0.45?

Option 1: 0.9

Option 2: 0.09

Option 3: 0.81

Option 4: 0.6

Team Careers360 21st Jan, 2024

Correct Answer: 0.9


Solution : $0.15 = \frac{15}{100}$
$0.18 =\frac{18}{100}$
$0.45 =\frac{45}{100}$
We know, LCM of fractions = $\frac{\text{LCM of numerators}}{\text{HCF of denominators}}$
So, LCM of $ \frac{15}{100}, \frac{18}{100}$, and $\frac{45}{100}=\frac{90}{100}=0.9$
Hence the correct answer is 0.9.
