- 45% of 300 + √? = 56% of 750 – 10% of 350
A. 260
B. 62500
C. 230
D. 52900
E. None of these
Answer & Explanation
Answer – B. 62500
Explanation :
45% of 300 + √x = 56% of 750 – 10% of 350
135 + √x = 420 – 35 => √x = 250
x = 62500 - [(?)11/7/50] = [20/(?)10/7]
A. 3
B. 5
C. 10
D. 20
E. None of these
Answer & Explanation
Answer – C. 10
Explanation :
[(?)11/7/50] = [20/(?)10/7]
x3 = 1000
x = 10 - 79296 ÷ √x =112*12
A. 3481
B. 3561
C. 3721
D. 3969
E. None of these
Answer & Explanation
Answer – A. 3481
Explanation :
√x = 79296 / 112*12
√x = 59
x = 3481 - 1637 + 1832 = (45)² + (?)²
A. 32
B. 38
C. 42
D. 48
E. None of these
Answer & Explanation
Answer – B. 38
Explanation :
1637 + 1832 = (45)² + (?)²
(?)² = 3469 – 2025 = 1444 => x = 38 - 13498 + 8932 – 1159 = ? * 89
A. 289
B. 271
C. 239
D. 261
E. None of these
Answer & Explanation
Answer – C. 239
Explanation :
13498 + 8932 – 1159 = ? * 89
x * 89 = 21271 => x = 239 - (37685 + 29452 – 41897) ÷ 250 = ?
A. 102.56
B. 118.96
C. 100.96
D. 112.76
E. None of these
Answer & Explanation
Answer –C. 100.96
Explanation :
(37685 + 29452 – 41897) ÷ 250
= 25240 ÷ 250 = 100.96 - 75 / ? = ? / 147
A. 175
B. 125
C. 115
D. 135
E. None of these
Answer & Explanation
Answer – E. None of these
Explanation :
x² = 75 * 147 => x = 105 - (32.4 * 8 * 5 + 4) ÷ 26 + 14 = (?)²
A. 8
B. 2
C. 18
D. 12
E. None of these
Answer & Explanation
Answer – A. 8
Explanation :
32.4 * 8 * 5 + 4 = 1300
1300 ÷ 26 + 14 = 64 => x = 8 - √(12 * 145 ÷ 6 + 34) = ?
A. 18
B. 28
C. 63
D. 73
E. None of these
Answer & Explanation
Answer – A. 18
Explanation :
√(12 * 145 ÷ 6 + 34)
= √(290 + 34)
= 18 - 5670 ÷ (28*13.5) = ?
A. 25
B. 35
C. 15
D. 45
E. None of these
