In the following table, the number of officers and clerks working in five different departments of an office is given. Read the table carefully and answer the questions given below it. Department Officer Clerk
By what percent is the number of officers more than that of clerks taking all the departments together ?
No. of officers in all departments = 145+12+136+164+148 = 745
No. of clerks in all departments = 125+128+124+126+122 = 625
Difference = 745-625 = 120
% by which no. of officers are greater than those of clerks = (120/625)*100 = 19.2%
