If 3(x - y) = 27 and 3(x + y) = 243, then x is equal to:
  1. 0
  2. 2
  3. 4
  4. 6
1 + 1 + 1 = ? 1 + x(b - a) + x(c - a) 1 + x(a - b) + x(c - b) 1 + x(b - c) + x(a - c)
  1. 0
  2. 1
  3. xa - b - c
  4. . None of these
Given that 100.48 = x, 100.70 = y and xz = y2, then the value of z is close to:
  1. 1.45
  2. . 1.88
  3. 2.9
  4. 3.7
(0.04)-1.5 = ?
  1. 25
  2. 125
  3. 250
  4. . 625
(17)3.5 x (17)? = 178
