Given,
5 x 4 ÷ 2 - 1
= 5 x 2 - 1
= 10 - 1
= 9
∴ Assertion (A) is false.
For simplifying an expression we use DMAS rule.
This statement correctly identifies the standard order of operations (Division, Multiplication, Addition, Subtraction) used in arithmetic.
∴ Reason (R) is true.
Hence, option 4 is the correct option.
