88, 112, 78, 120, 64,

193. 69 + 200.09 – 512.96 + 312.09 =?

{(300 ÷ 15)% of 1500} ÷ 6 = ? + 120 

Simplify the following expressions and choose the correct option.

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

125% of 129 ÷ 43 × 28 ÷ 7 = ? ÷ √16

31% of 1900 - ? = 7³

(160 × 12 - 13 × 20)/(120 × 2 + 2 × 35 + 2 × 11) = ?

Find the value of ‘x’ if (5 × 196 – 340 ÷ 17) ÷ 20 = √1600 – x.

? = (22% of 25% of 60% of 3000) + 21

If x + y + 3 = 0, then find the value of x³ + y³ – 9xy + 9.
