On simplification, 3034 – (1002 20.04) is equal to:

E= (2 x 5 x 10)/(1600)^1/2
W = (4 x 5 x 16)/(32 x 50)^1/2

88% of 370 + 24% of 210 - ? = 118

6999 + 3555 - 2333 = ?

The H.C.F of 2⁴ x 3² x 5³ x 7, 2³ x 3³ x 5² x 7² and 3 x 5 x 7 x 11 is:

The unit’s digit in the product (3127)¹⁷³ is;

(2.4 x 10³) + (8 x 10^-2) = ?

If  x *y=x² + y² – xy, then the value of 9*11 is:

The least number, which when divided by 12, 15, 20 and 54 leaves in each case a remainder of 8, is:
