3/4 of a number is 60 more than its 1/3. The number is:
Answer: B
Let the number be x.
The equation is \(\frac{3}{4}x = \frac{1}{3}x + 60\).
\(\frac{3}{4}x - \frac{1}{3}x = 60\).
The LCM of 4 and 3 is 12.
\(\frac{9x - 4x}{12} = 60\).
\(\frac{5x}{12} = 60\).
\(x = 60 \times \frac{12}{5} = 12 \times 12 = 144\).
