What is the arithmetic mean between x - 3 and x + 3?
Correct answer: C
Explanation and memory cue
The arithmetic mean of two numbers is their sum divided by 2. Here, (x-3 + x+3)/2 = (2x)/2 = x, so the mean is x.
The Federal Investigation Agency recruits across a wide range of grades, from Constable and clerical staff to Inspector and Assistant Director, and each grade has its own written test. This hub brings together more than 3,200 published questions transcribed from FIA past papers spanning 2002 to 2022, organised by post and then by paper. Inspector, Assistant Director and Sub Inspector are the most heavily represented posts; UDC, LDC, Assistant, ASI and the Assistant Director Investigation and Legal posts have fewer papers but are all live.
Across posts, the recurring subjects are Pakistan Studies, Islamic Studies, English, General Knowledge, Mathematics and Everyday Science, with computing questions weighted towards the clerical and Cyber Crime Wing tests. The recruitment tests have been conducted by different testing agencies in different years, and where the paper metadata records that, it appears in the paper name. Start with the post you are applying for and attempt its most recent paper first; the older papers show how the pattern has shifted over time.
