The correct answer is B
136% of 560 - 2/7 of 630 + 45% of 420 =?
((12+12+12+12)÷4)/((8+8+8+8+8+8)÷16) = ?
?2 - (40% of 240) = 25 X 5
135÷ 15 x 19 + 14807 = ? + √3249 - √9604
?% of 120 × 3√343 = 42 × 20
(21 × 16 – 8) ÷ 41 = ?
262 × 15 + (?)² = 4099
2945 – 1508 + 3454 = ? + 2255
52% of 400 + √(?) = 60% of 600 - 25% of 400
(506 ÷ 22 + 9 × 3) × ? = 900 ÷ 9
