Simplify the following expressions and choose the correct option.
18² + (27 ÷ 3) × 11 − 250 = ?
√144 × √121 + 25% of 600 = ? + 256
Simplify the following expression:-
What will come in the place of question mark (?) in the given expression?
? × 18 + 3072 ÷ 24 = 20% of 1900Â
Simplify the following expression:
  (525 +175) ² - (525 – 175) ² / (525 × 175)
? = 6.25% of 240 + 25 2 + 17 2 – 16 × 17
(8.4 × 6.5 ×2.52 )/(5.04 ×3.25 ×2.1) = ?
Simplify: 3/4 of 2½ + 2/3 of 1½
