?% of (√196) × 24 + 344 = 428

600 ÷ 8 + 12 % of 250 + ? * 14 = 50 * √49

666(2/3)% of 30 - 116(2/3)% of 90 =?

41.66% of 888 + 66.66% of 1176 = ?² - ⁴√ 16  

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

(30% of 400 - 20% of 540 + 35% of 1000) = ?

672 ÷ 28 × 24 + 363 – 309 =?

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

(320 ÷ 8 + 22) × 4 = 60 + 40% of ?

(8.4 × 6.5 ×2.52 )/(5.04 ×3.25 ×2.1) = ?
