What will come in place of question mark in the following question?

30% of [{(320% of 20) - 14} % of 340] = 200% of ?

A 17.5

B 25.5

C 27

D 51.5

E None of these

Correct Answer: Option B

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, and in the bracket, the BODMAS rule must be followed,

⇒ 30% of [{(320% of 20) - 14} % of 340] = 200% of ?

⇒ 30% of [{(320 × 20/100) – 14} % of 340] = 200% of ?

⇒ 30% of [{64 – 14)} % of 340] = 200% of ?

⇒ 30% of (50% of 340) = 200% of ?

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

⇒ 30% of 170 = ? × 200/100

⇒ 51 = 2 × ?

⇒ ? = 25.5

Hence the required answer is 25.5
