CTET Paper I (Classes I to V) 2 Feb 2023 Solved Paper

Concept:We apply the BODMAS rule: brackets, orders (powers and roots), division and multiplication (from left to right), addition and subtraction (from left to right).Explanation:First, do all multiplications and divisions from left to right.Calculate $16.5 \times 3 = 49.5$.Calculate $35 \div 5 = 7$.Calculate $3 \times 13.5 = 40.5$.The expression becomes: $49.5 - 7 - 40.5$.Now subtract from left to right: $49.5 - 7 = 42.5$, then $42.5 - 40.5 = 2$.So the value is $2$.Answer:2 (Option A)
