Directions:(1-10) What value will come in place of question mark (?) in the following questions?

1. Question

(30)3 ÷ 36 x 42 ÷ 14 = 202 + 2?

Ans: 3
27000 ÷ 36 x 42 ÷ 14 = 202 + 2?
=> 750 x 3 = 202 + 2?
=> 2250 = 202 + 2?
=> 2048 = 2?
=> 211 = 2?
=>? = 11

2. Question

(37)9 x (33)8 ÷ (243)? = 98.5

Ans: 1
(37)9 x (33)8 ÷ (35)? = (32)8.5
=> 363 x 324 ÷ 35x? = 317
=> 35x? = 363+24-17 = 370
=> ? = 14

3. Question

7296 ÷ 128 + 10080 ÷ ? – 28000 ÷ 175 = 37

Ans: 4
57 + 10080 ÷ ? – 160 = 37
=> 10080 ÷ ? = 37 – 57 + 160 = 140
=> ? = 10080 ÷ 140 = 72

4. Question

144 x 12.5 + 22.5 x 40 = 163 – ?

Ans: 3
1800 + 900 = 4096 – ?
=> ? = 4096 – 2700 = 1396

5. Question

19 x 25 + 64% of 950 = 45 x 20 + ?

Ans: 1
475+608 = 900 + ?
? = 1083-900 = 183

6. Question

25% of 84 + 28.57% of 245 + 88.88% of 117 = ?

Ans: 5
We note that 25% = 1/4, 28.57% = 2/7, 88.88% = 8/9
So, ? = 84 x (1/4) + 245 x (2/7) + 117 x (8/9)
= (4 x 21) x (1/4) + (7 x 35) x (2/7) + (9 x 13) x (8/9)
= (1 x 21) + (2 x 35) + (8 x 13) = 195

7. Question

∛125 – ∛9261 – ∛3375 = ?

Ans: 2
53 = 125, 213 = 9261, 153 = 3375
? = ∛125 – ∛9261 – ∛3375
= 5 – 21 – 15 = -31

8. Question

(0.512)114 ÷ 0.6453 = (0.8)?

Ans: 1
(0.83)114 ÷ (0.82)53 = (0.81)?
(0.8)(3×114 – 2×53) = (0.81)?
So, ? = (3×114 – 2×53 )/1 = 236

9. Question

372 – 442 + 392 = ?

Ans: 5
? = 372 – 442 + 392
= 1369 – 1936 + 1521 = 954

10. Question

80% of 310 – 20% of 320 = ?

Ans: 5
? = (80 x 310/100) – (20 x 320/100)
= (24800/100) – (6400/100)
= 248 – 64 = 184
