Answer»

Follow BODMAS RULE to solve this question, as per the order given below,

Step - 1 - Parts of an equation enclosed in 'Brackets' must be solved FIRST,

Step - 2 - Any mathematical 'Of' or 'Exponent' must be solved next,

Step - 3 - Next, the parts of the equation that contain 'Division' and 'Multiplication' are CALCULATED,

Step - 4 - Last but not LEAST, the parts of the equation that contain 'Addition' and 'Subtraction' should be calculated.

x = 172 + [(132 ÷ 6 × 5 + 78 × 4 ÷ 3) - {125 ÷ (160 ÷ 32) + 7}]

⇒ x = 172 + [(22 × 5 + 312 ÷ 3) - {125 ÷ 5 + 7}]

⇒ x = 172 + [(110 + 104) - {25 + 7}]

⇒ x = 172 + [214 - 32]

⇒ x = 172 + 182

⇒ x = 354
