The correct Answer is:
To determine if the statements \( 40 \text{ persons} : 200 \text{ persons} = Rs. 15 : 75 \) are true, we will compare the two ratios step by step. ### Step 1: Express the Left-Hand Side (LHS) as a Fraction The left-hand side is \( 40 \text{ persons} : 200 \text{ persons} \). We can express this ratio as a fraction: \[ \text{LHS} = \frac{40}{200} \] ### Step 2: Simplify the LHS Fraction To simplify \( \frac{40}{200} \), we can divide both the numerator and the denominator by their greatest common divisor (GCD), which is 40: \[ \frac{40 \div 40}{200 \div 40} = \frac{1}{5} \] ### Step 3: Express the Right-Hand Side (RHS) as a Fraction The right-hand side is \( Rs. 15 : 75 \). We can express this ratio as a fraction: \[ \text{RHS} = \frac{15}{75} \] ### Step 4: Simplify the RHS Fraction To simplify \( \frac{15}{75} \), we can divide both the numerator and the denominator by their GCD, which is 15: \[ \frac{15 \div 15}{75 \div 15} = \frac{1}{5} \] ### Step 5: Compare the Two Fractions Now we have: \[ \text{LHS} = \frac{1}{5} \quad \text{and} \quad \text{RHS} = \frac{1}{5} \] Since both fractions are equal, we conclude that: \[ 40 \text{ persons} : 200 \text{ persons} = Rs. 15 : 75 \] ### Conclusion Thus, the statement is **TRUE**. ---
