Option E
(24.99)^2 – 1874.98% of 19.98 = ?
=> ? = 25^2 – 20% * 1875
=> ? = 625 – 375
=> ? = 250

2. ?% of 1799.98 = 75% of 479.99 + 90.11

Option B
?% of 1799.98 = 75% of 479.99 + 90.11
=> ?% of 1800 = 75% *480 + 90
=> ?*18 = 450
=> ? = 25

Option B
11.98% of 824.98 =20% of ? + 24.98% of 239.97
=> 12% of 825 = 20% of ? + 25% of 240
=> 0.20*? + 60 = 99
=> ? = 195

4. ? + 765.87 – 526.01 = 25*23.98

360
300
310
Option C
? + 765.87 – 526.01 = 25*23.98
=> ? + 766 – 526 = 25*24
=> ? + 240 = 600
=> ? = 360

Option D
(400% of 49.89)/24.98 = ?^2 – (1680.99)^1/2
=> ?^2 – (1681)^1/2 = (400% of 50)/25
=> ?^2 = 8+ 41
=> ? = 7

6. (728.99)^1/2 + (?)^1/2 = (1331)^1/3

Option B
(728.99)^1/2 + (?)^1/2 = (1331)^1/3
=> 27 + (?)^1/2 = 11
=> ? = 49

7. ? = 24.99% * 959.97 + 29.98% of 199.98
300
285
270
299
310
Option A
? = 24.99% * 959.97 + 29.98% of 199.98
=> ? = 25% of 960 + 30% of 200
=> ? = 240 + 60
=> ? = 300

8. 20.01% of 164.99 = 44.98% of 79.98 – (?)^1/2

Option C
20.01% of 164.99 = 44.98% of 79.98 – (?)^1/2
=> (?)^1/2 = 45% of 80 – 20% of 165
=> (?)^1/2 = 36 – 33
=> ? = 9

9. 17.99 * 20.98 – 14.98*11.99 = ? * 8.98

Option D
17.99 * 20.98 – 14.98*11.99 = ? * 8.98
=>18*21 – 15*12 = ?*9
=> ?*9 = 378 – 180
=> ? = 22

10. (19.98% of 559.98)/13.99 = ? – 11.98% of 399.99

Option E
(19.98% of 559.98)/13.99 = ? – 11.98% of 399.99
=> (20% of 560)/14 = ? – 12% of 400
=> 112/14 = ? – 48
=> ? = 56
