Directions:(1-10) What value should come in place of the questions mark (?) in the following questions?
1. Question
7960 + 2956 – 8050 + 4028 = ?
? = 7960 + 2956 – 8050 + 4028 = 6894
2. Question
350% of ? ÷ 50 + 248 = 591
3.5 x ? ÷ 50 = 591-248 = 343
=> ? = 343 x 50/3.5 = 4900
3. Question
36% of 365 + ?% of 56 = 156.6
0.36 x 365 + ? x 0.56 = 156.6
=> 131.4 + ? x 0.56 = 156.6
=> ? x 0.56 = 25.2
=> ? = 45
4. Question
(17)2 X √1936 – 155 X ? = -2009
289 x 44 – 155 x ? = – 2009
=> 155 x ? = 289 x 44 + 2009
= 12716 + 2009 = 14725
? = 14725/155 = 95
5. Question
856 + 22 x 53 – 3354 ÷ 13 = (?)2
856 + 1166 – 258 = (?)2
(?)2 = 1764
=> ? = √1764 = 42
6. Question
(0.027)2 ÷ (0.09)5 x (0.0081) = (0.3)?+4
(0.3)6 ÷ (0.3)10 x (0.3)4 = (0.3)?+4
=> (0.3)0 = (0.3)?+4
=> ?+4=0
=> ? = -4
7. Question
(256 x 49)1/2 + 192 + 11 = (?)2
(?)2 = 16×7 + 361 + 11
= 112+361+11 = 484
=> ? = ±22
8. Question
19 x 12 – 106 + 188 – 618 ÷ 6 = ?
? = 228 – 106 + 188 – 103 = 207
9. Question
(?)2 = (122 x 16 ÷ 24 + 193 + 7 x 5)½
(?)2 = (144 x 16/24 + 228)½
(?)2 = (96 + 228)½
(?)2 = (324)½
? = √18 = 3√2
10. Question
252 x √31.36 ÷ √0.64 = 36 x (?)2
(?)2 x 36 = 252 x 5.6 ÷ 0.8 = 252 x 7
=> (?)2 = 7 x 7 = 49
=> ? = 7
