Answers:
1. 3
The series is
5^3 – 1 = 124
6^3 – 1 = 215
7^3 – 1 = 342
8^3 – 1 = 511
9^3 – 1 = 728
10^3 – 1 = 999
Reqd answer = 728

√5599 / 3√3370 = ?
75 ÷ 15 = ?
? = 5

(3525 + 5567 + 9853) ÷ (3132 + 1975 + 2275) × 7 = ?
18945 ÷ 7382 × 7
2.57 × 7 = 17.99 18
8. 4
√25000 * √3.999 = 4
158 × 2 = 316
9. 2
[4/5 * (2/7 * 5/3) / 7/9] of 347 =4/5 * 10/21 * 9/7 * 347 = ?
10. 3
(13.98)^2 + 272% of 75 = ?
196 + 272 * 3/4 = ?
196 + 204 = ?
? = 400
