Consider the following frequency distribution:
If the total of the frequencies is 100 and mode is 25 , then which one of the following is correct?

Options

  1. Ax=2yx=2 y
  2. B2x=y2 x=y
  3. Cx=yx=y
  4. Dx=3yx=3 y

Correct answer

C. x=yx=y

Step-by-step solution

14+x+27+y=15=100x+y=44∴x=y is only possibility \begin{aligned} & 14+x+27+y=15=100 \\ & x+y=44 \\ & \therefore x=y \text{ is only possibility }\end{aligned}
