The simplified value of
$${{1\over 3}÷{1\over 3}×{1\over 3}\over{1\over 3}÷{1\over 3}of{1\over 3}}-{1\over 9}$$

What is the value of X ?, if 7580 - X = 3440

If 3x + 7y=75, 5x- 5y= 25, then the value of (x +y)=?

The value of  

Direction: what should come in place at question mark(?).

45% of 224×?% of 120=8104.32

If 551 ÷ 29 = 19 then 5.51 ÷ 0.0019 = ?

(0.04)^-1.5 on simplification gives: 

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

125% of 2440 – 75% of 1856 = ?
