Arrange the letters of each group to make a meaningful

62 of 8 - 320 ÷ 4 = ?³ + 200

? × 5.5 = √1225 + 40% of 30% of 37.5% of 5000 – 6³

(22² × 8²) ÷ (92.4 ÷ 4.2) =? × 32

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

Find the simplified value of the given expression:

8 of 7 ÷ 2 × 5² + √36 – 10

If a³ - b³ = (a - b)(a² + ab + b²), find a³ - b³ when a = 10 and b = 4.

1555.5 + 1000.8 – 1354.3 = ? + 52

15% of 695 – 12.5% of 250 =? – 1200

(18% of 360) ÷ 0.4 = ?

116*2/3% of 18600 + 666*2/3% of 1290 = 457*1/7% of 1750 + 555*5/9% of 3150 + ?
