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

Ans: 2
? – 31 = 391 + 384 – 576 = 199

=> ? = 199 + 31 = 230

##### 2. Question

152 + 132 + 172 + 212 = ?

Ans: 5
? = 225 + 169 + 289 + 441 = 1124

##### 3. Question

16.5 x 16 + 24.5 x 18 – 3.7 x 40 = ?

Ans: 5
? = 264 + 441 – 148 = 557

##### 4. Question

142 + 112 + 172 + 132 = ?

Ans: 2
? = 196 + 121 + 289 + 169 = 775

##### 5. Question

144 x 3.75 – 112 x 784 ÷ 224 =?

Ans: 5
? = 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 = ?

Ans: 2
213 = 9261, 103 = 1000, 223 = 10648

? ≈ ∛9261 + ∛1000 + ∛10648

= 21 + 10 + 22 = 53

##### 7. Question

(19.99)2 – (31.93)2 – (16.07)2 = ?

Ans: 2
? ≈ 202 – 322 – 162

= 400 – 1024 – 256

##### 8. Question

(34.97)2 – 25.07 = ? x 29.99

Ans: 4
? = (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?
