C. 3
D. 4
E. None of these
Answer & Explanation
Answer – D. 4
Explanation :
(√3 + 1)² = ? + √12
3 + 2√3 + 1 = ? + 2√3 = 4 - 621 ÷ 27 * 2 – 37 = √?
A. 3
B. 9
C. 81
D. 121
E. None of these
Answer & Explanation
Answer – C. 81
Explanation :
621 ÷ 27 * 2 – 37 = √?
23 * 2 – 37 = √? = 9
x = 81 - √? + 43 = √19881
A. 9216
B. 8464
C. 9604
D. 8836
E. None of these
Answer & Explanation
Answer – C. 9604
Explanation :
√? + 43 = √19881
√? = 141 – 43
x = 9604 - 325 – (12)² + 75 = (?)² – 68
A. 324
B. 384
C. 12
D. 18
E. None of these
Answer & Explanation
Answer – D. 18
Explanation :
325 – (12)² + 75 = (?)² – 68
325 – 144 + 75 + 68 = (?)²
(?)² = 324
x = 18 - (62.5 * 14 * 5) ÷ 25 + 41 = (?)³
A. 4
B. 6
C. 5
D. 8
E. None of these
Answer & Explanation
Answer – B. 6
Explanation :
(62.5 * 14 * 5) ÷ 25 + 41 = (?)³

(?)³ = 216
x = 6 - 48356 + 5412 – 736 = ? * 40
A. 1302.6
B. 1218.9
C. 1325.8
D. 1412.5
E. None of these
Answer & Explanation
Answer –C. 1325.8
Explanation :
48356 + 5412 – 736 = x * 40
53032 = x * 40
x = 1325.8 - 538.24 – 193.42 + 343.91 = ?
A. 725.63
B. 851.13
C. 688.73
