60% of (15% of 2500 + 40% of 2500 + 20% of 2500) = ?2 – 100
a. 25
b. 40
c. 45
d. 35
e. 55
Answer: d
Solution:
60% of (15% of 2500 + 40% of 2500 + 20% of 2500) = ?2 – 100
0.60 × (0.15 × 2500 + 0.40 × 2500 + 0.20 × 2500) + 100 = ?2
0.60 × (375 + 1000 + 500) + 100 = ?2
?2 = 1225
? = 35
Hence, option d.
1000÷ 250 = (3√? × √1444) ÷ (3√512 × √361)
a. 2744
b. 5412
c. 4096
d. 512
e. 3375
Answer: c
Solution:
1000÷ 250 = (3√? × √1444) ÷ (3√512 × √361)
4 = (3√? × 38) ÷ (8 × 19)
38 × 3√? = 4 × 8 × 19
3√? = 16
? = 4096
Hence, option c.
14% of 300 + 12% of 450 – 25% of √(92 – √289) = ?
a. 94
b. 98
c. 115
d. 84
e. 78
Answer: a
Solution:
14% of 300 + 12% of 450 – 25% of √(92 – √289) = ?
0.14 × 300 + 0.12 × 450 – 0.25 × √(81 – 17) = ?
42 + 54 – 2 = ?
? = 94
Hence, option a.
[(6√3 × 5√2) × (2√2 × 8√3) ÷ 16] = ?
a. 200
b. 160
c. 192
d. 165
e. 180
Answer: e
Solution:
[(6√3 × 5√2) × (2√2 × 8√3) ÷ 16] = ?
[(30√3 × √2) × (16√2 × √3) ÷ 16] = ?
30 × 3 × 2 × 16 ÷ 16 = ?
? = 180
Hence, option e.
3√3375 × 12.5% of 8040 – (162 × ?2) = 2531
a. 4
b. 16
c. 11
d. 7
e. 22
Answer: d
Solution:
3√3375 × 12.5% of 8040 – (162 × ?2) = 2531
2531 = 15 × 1005 – (256 × ?2)
(256 × ?2) = 15075
256 × ?2 = 12544
?2 = 49
? = 7
Hence, option d.
