The value of 43-3× (4×6+12/3 ×6-4×5) +4?

13 X ? = 85 X 4 + √81 + 2

What will come in the place of question mark (?) in the given expression? 

48 ÷ 4 × (3 + 5) – 6² + 10 = ?

5.45% of 1854 – 37.5% of 1096 = ? – 48% of 630

72% of 486 – 64% of 261 = ?

20% of 450 - 15% of 400 = 25% of ?

56 × 18 + ? × 21 – 49 × 12 = 63 × 26 

Simplify the following expressions and choose the correct option.

[(2/3 of 270) ÷ 9] + [(5/6 of 96) ÷ 8] = ?

(21 X 5) + ? = (480 - 120) ÷ 3
