RRB ALP CBT I 26 Nov 2024 Shift 1 Paper

Concept:The order of operations (BODMAS/PEMDAS) decides which calculation is done first in an expression with mixed operations.Explanation:Here, the expression is $13 - 12 \div 4 \times 2$.According to BODMAS/PEMDAS, division and multiplication have the same priority, so we perform them from left to right before subtraction.First, carry out the division: $12 \div 4 = 3$.Next, multiply the result by $2$: $3 \times 2 = 6$.Now, the expression becomes $13 - 6$.Finally, perform the subtraction: $13 - 6 = 7$.Thus, the value of the given expression is $7$.Answer:Option C, which is $7$.
