846
678
768
456
Option B
132 ÷ 6 × 12.5 – x – 12 % of 50 + 93 = 152

(132 / 6) * (25/2) – (12/100) * 50 + 729 – 152 = x

275 – 6 + 729 – 152 = x

x = 846

Option D
∛148877 – √5184 + 18 % of 150 + 133 = x + 28

53 – 72 + (18/100) * 150 + 2197 – 28 = x

x = 53 – 72 + 27 + 2197 – 28

x = 2177

9. 18 × 3 7/9 of (? ÷ 104) of 728 = 3808

8
5
4
Option C
18 × 3 7/9 of (x ÷ 104) of 728 = 3808

18 * (34/9) * (x/104) * 728 = 3808

x = 8

10. (51120 ÷ 9) + (3/11) of 1155 = 25 % of ?

24980
13980
23900
23880
23980
Option E
(51120 ÷ 9) + (3/11) of 1155 = 25 % of x

(51120/9) + (3/11) * 1155 = (25/100) * x

5680 + 315 = (x/4)

5995 * 4 = x

x = 23980
