Directions:(1-5) What value will come in place of question mark (?) in the following questions?
1. Question
23 x 17 + 24 x 16 – 32 x 18 = ? – 31
? – 31 = 391 + 384 – 576 = 199
=> ? = 199 + 31 = 230
2. Question
152 + 132 + 172 + 212 = ?
? = 225 + 169 + 289 + 441 = 1124
3. Question
16.5 x 16 + 24.5 x 18 – 3.7 x 40 = ?
? = 264 + 441 – 148 = 557
4. Question
142 + 112 + 172 + 132 = ?
? = 196 + 121 + 289 + 169 = 775
5. Question
144 x 3.75 – 112 x 784 ÷ 224 =?
? = 144 x 3.75 – 112 x 3.5
= 540 – 392 = 148
6. Question
Directions:(6-8) What approximate value will come in place of question mark (?) in the following questions? (You are not expected to calculate the exact value.)
∛9259.96 + ∛1000.7 + ∛10646.52 = ?
213 = 9261, 103 = 1000, 223 = 10648
? ≈ ∛9261 + ∛1000 + ∛10648
= 21 + 10 + 22 = 53
7. Question
(19.99)2 – (31.93)2 – (16.07)2 = ?
? ≈ 202 – 322 – 162
= 400 – 1024 – 256
8. Question
(34.97)2 – 25.07 = ? x 29.99
? = (352 – 25)/30
= (1225 – 25)/30
= 1200/30 = 40
9. Question
Directions:(9-10) What value will come in place of question mark (?) in the following question?
√9216 – √8649 – √8836 = ?
962 = 9216, 932 = 8649, 942 = 8836
? = √9216 – √8649 – √8836
= 96 – 93 – 94 = -91
10. Question
(38)2 – (33)2 + (32)2 = ?
? = 382 – 332 + 322
= 1444 – 1089 + 1024
= 1379
