• Quant Statistics

In an asymmetrical-distribution, if the mean and median of the distribution are 270 and 220 respectively, then the mode of the data is

1. 120
2. 220
3. 280
4. 370

Answer

The relation between mean, median and mode is:

Mean - Mode = 3(Mean - Median)

Mode = 3×Median - 2×Mean

= 3×220 - 2×270

= 10(66 - 54)

= 120

The correct option is A.
