How many states are there in

5/2 of 5/6 of 12/5 of 54 % of 5250 = ?

?% of (√196) × 24 + 344 = 428

961 × 4 ÷ 31 – 15% of 180 = ? – 7³

(75 + 0.25 × 10) × 4 = ?² - 14

(64/25)^? × (125/512)^?-1 =  5/8

Simplify the following expression:

    (400 +175) ² - (400 – 175) ² / (400 × 175)

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

34 X 11 - ? + 36 = 3 X 75 + 125

√256 × 25 – 15 × 14 =?

Find the simplified value of the given expression.

18 ÷ 3 + {(48 ÷ 6) of 12} + 10 - 8 of 9
