Total number of employees=50

Median bonus amt =(25+26th term)/2=(100+100)/2=100

Mean bonus amt=Total bonus amt/Total number of employees

=7(50)+37(100)+4(150)+2(200)/50

=101

Modal bonus amt(ie) bonus amt occuring more in the set=100

m=100,n=101,p=100

Option B confusing.

m<n=p means m<n and m=p

Pick B
