Find the simplified value of the given expression:

(125 - 75 ÷ 3 of 5) ÷ 2 + 4 of 12 ÷ 3 - 16 of 5 ÷ 20

1549.8 ÷ 8.2 + 65.6 × 55 = (? × 4) + (42 × 30.5)

420 ÷ 7 + 140 % of 20 + ? × 13 = 18 × 15

What will come in place of ‘?’ in the given expression : 

? – (22 × 25 + 70% of 160) = 27²

15 * 12 + 35% of 80 + 70% of 130 = ?

What is the value of (15²+8²) ÷17

(25.111 % of 200) × 26 ÷ 12.99 – 18.88 × 15.82 + 150.33% of ³√ 4917 = ? – 200

12.5% of (100 + ?) = 40

(3984 ÷ 24) x (5862 ÷ 40) = ?

675 ÷ 15 + 225 – 18 × 6 = ?
