Solution

The correct option is C 13
Let the number be x, then the sum of two times x and three is equal to eleven times x.
2x+3=11x

Step 1: Subtract both sides of the equation by 3 to eliminate 3 on the left side of the equation.
2x+33=11x32x=11x3

Step 2: Subtract both sides of the equation by 11x to eliminate 11x on the right side of the equation.
2x11x=11x311x
9x=3

Step 3: Now, divide both sides by -9 to eliminate -9 on the left side of the equation.
9x9=39x=13

Hence, the required number is 13.
