Which of the following statements is true about

187 ÷ 5 ÷ 0.4 = ? – 24 × 2.4

30% of 2200 +’?’ x 50 – 1020 = 11x 306 +  (√ 2250 ÷ 0.1)  

Simplify: 72 − 18 ÷ 3 × 2 + 5 × 3

43.5 × [1/7 × (91 - 49) + 17(1/3)] = ?

Find the simplified value of the given expression.

What value should come in the place of (?) in the following questions?

(1728)^(1/3) + √441 + √1089 = ? × 5 + 11

Simplify: 3/4 of 2½ + 2/3 of 1½

√10000 × √8100 - (50)² = √(?) + (80)²

Simplify-

x + 3(y + x – 2) – (x + y).

125 + 30% of 250 + √576 = ?
