Which of the following is not true about capital

What is the value of ‘x’ if x% of 720 added to {2160 ÷ x of 20} × 2 gives 180?

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

35 X 72 + 35 X 28 = ? X √16 

`(sqrt(1296)xx42)/(120+200)` = ?

(√529 + 6³ /8)% of 800 = ?% of 250

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

(√1089 + √484) X 5 + ? = 725

Simplify the following expression:

25.6% of 250 + √? = 119     

What value should come in place of the question mark (?) in the following question?
