The correct Answer is:
To solve the problem step by step, let's denote the certain number as \( x \). 1. **Identify the correct and incorrect calculations**: - Ramesh was supposed to find \( \frac{3}{14} \) of \( x \). - Instead, he found \( \frac{3}{4} \) of \( x \). 2. **Set up the equations**: - The correct answer (what he was supposed to find) is: \[ \text{Correct Answer} = \frac{3}{14} x \] - The incorrect answer (what he actually found) is: \[ \text{Incorrect Answer} = \frac{3}{4} x \] - According to the problem, the incorrect answer is 50 more than the correct answer: \[ \frac{3}{4} x = \frac{3}{14} x + 50 \] 3. **Eliminate the fractions**: - To eliminate the fractions, we can multiply the entire equation by 28 (the least common multiple of 4 and 14): \[ 28 \cdot \left(\frac{3}{4} x\right) = 28 \cdot \left(\frac{3}{14} x + 50\right) \] - This simplifies to: \[ 21x = 6x + 1400 \] 4. **Rearranging the equation**: - Now, we can rearrange the equation to isolate \( x \): \[ 21x - 6x = 1400 \] \[ 15x = 1400 \] 5. **Solving for \( x \)**: - Divide both sides by 15: \[ x = \frac{1400}{15} \] - Simplifying \( \frac{1400}{15} \): \[ x = \frac{280}{3} \quad \text{(which is equal to } 93 \frac{1}{3} \text{)} \] Thus, the number is \( 93 \frac{1}{3} \).
