1. D; Series is -99, -89, -79, -69, -59.

2. A; Series is x1 + 11, x2, + 21, x3 + 31, x4 + 41.

3. B; Series is + 11 x 11, +10 x 10, +9 x 9, +8 x 8

4. D; Series is x9+9, x8+8, x7+7, x6+6

5. A; Series is +91, +81, + 71, +61.

6. E
Total emp = 940 x 100/23.5 = 4000
∴ Total(A) = 20/100 x 4000 = 800
∴ Female(A) = 37/100 x 800 = 296
∴ Male(A) = 504
Similary, for other companies we get total females = 1796 And total males = 2204
∴ Difference = 408

7. D; Required % =296/128 x 100 = 231.25%

8. B
Male (A + B + C) = 504 + 517 + 356 = 1377
Female (D + E + F) = 192 + 122 + 407 = 721
∴ Difference = 1377 – 721 = 656

9. B; Required % = 712/800 x 100 = 89%

10. D
Female(B) = 423;
Male(F) = 333
∴ Ratio = 333/423 = 37/47
