6. √16383.56 ÷ 3.99 × 15.89 = ? – 18311.88 ÷ 11.99 + 141.89
1234
1879
1842
1456
1786
Option C
√16384 ÷ 4 × 16 = x – 18312 ÷ 12 + 142
(128/4) * 16 = x – (18312 / 12) + 196
512 = x – 1526 + 196
x = 512 + 1526 – 196 = 1842

7. (6.99/8.99) of 4067.99 + 76.99 % of 1199.99 = (?)2 – (127.89 ÷ 15.99)

64
65
66
67
Option B
(7/9) * 4068 + (77/100) * 1200 = x2 – (128/16)
3164 + 924 + 8 = x2
x2 = 4096
x = 64

8. (8.23 × 8.007)^5 ÷ (511.8 ÷ 7.99)^2 × (7.56 × 64)^3 = (8.008)^(? + 4.5)

20
25
12
Option A
(8^2)^5 ÷ (512/^8)^2 × (8 × 8^2)^3 = (8)^x + 5
8^10 ÷ (64)^2 × (8^3)^3 = (8)^x + 5
8^10 ÷ 8^4 × 8^9 = (8)^x + 5
8^10 – 4 + 9 = 8^x + 5
8^15 = 8^x + 5
15 = x + 5
x = 10

9. ? % of (74.99 × 3.89 – 149.99) = 419.88 + 74.5^2
1020
2040
4030
6070
3050
Option C
x % of (75 × 4 – 150) = 420 + 75^2
(x/100) * (300 – 150) = 420 + 5625
(x/100) * 150 = 6045
3x/2 = 6045
x = 6045 * (2/3) = 4030
