What is the mean value of the following set of data?

What will come in the place of question mark (?) in the given expression? 

(240% of 175 ÷ √16) X 6 + 80% of 400 = ?³ + 179 + 42

14% of 700 + 15% of 900 + 10% of 160 = ?

What will come in the place of question mark (?) in the given expression?

? = (27 × 13) – 26% of (41² – 9² )

4.7 × 3.5 + 4.2 × 4.5 = 22.5 × 3.5 - ?

Find the simplified of the following expression:

Simplify:

18 × √225 + 378 ÷ √441 = ? × 9 

119 ÷ [22 - {90 ÷ (23 - 105 ÷ (7 × 3))}] = ?

[(82 × 162)/12] - 28 = ?
