NDA Subject-Verb Agreement

Trick 1 - FANBOYS Rule for Subjects: When subjects joined by 'For, And, Nor, But, Or, Yet, So' - only 'And' makes it plural, others follow proximity rule. Trick 2 - Percentage/Fraction Formula: Percent/Fraction + OF + Singular noun = Singular verb Percent/Fraction + OF + Plural noun = Plural verb Example: 50% of the water IS pure / 50% of the students ARE present Trick 3 - Distance/Time/Money Rule: When talking about total amount as ONE unit = Singular verb Example: Five kilometers IS a long distance (not 'are') Most Common Trap (#1 Student Mistake): Students get confused by words between subject and verb. Always identify the MAIN subject, ignore the words in between

'The bag of books are heavy' (thinking 'books' is subject) Correct: 'The bag of books IS heavy' (subject is 'bag', not 'books') Quick Identification Method: Cross out prepositional phrases (of, in, on, at, with, by, for) to find the real subject. 'The leader of all political parties' → Cross out 'of all political parties' → Subject is 'leader' (singular) Special Cases to Remember: - None can be singular or plural depending on context - Each, every, either, neither are always singular - Data can be singular (modern usage) or plural (traditional) - Scissors, trousers, spectacles are always plural Exam Success Strategy: In error detection questions, immediately scan for subject-verb mismatches. This appears in 60% of grammar-based error detection questions in SSC CGL. Practice identifying the main subject by eliminating prepositional phrases and modifying clauses.
