    A) 303
    B) 345
    C) 388
    D) 457
    E) 429
    View Answer
      Option E
    Solution:
    60% of 2535 = 1521
    832 ÷ 13= 64
    – 342 = – 1156
  2. √1765 + 1010 ÷ 14 – 64% of 250 = x
    A) -46
    B) -26
    C) 32
    D) -33
    E) 39
    View Answer
      Option A
    Solution:
    √1765 = 42
    1010 ÷ 14 = 72
    – 64% of 250 = 160
  3. 795.009 ÷ 15.234 + 768.123 ÷ 12.099 + 63.98 ÷ 4 – 1272.985 ÷ 19.195 = x
    A) 62
    B) 66
    C) 75
    D) 81
    E) 78
    View Answer
      Option B
    Solution:

    795 ÷ 15 = 53
    768 ÷ 12 = 64
    64 ÷ 4 = 16
    – 1273 ÷ 19 = -67
  4. √x + 36.09% of 350 – 16.009 × 22.897 = -(14)2 
    A) 2068
    B) 2025
    C) 2749
    D) 2116
    E) 2209
    View Answer
      Option D
    Solution:
    36% of 350 = 126
    16*23 = 368
    -(14)2 = -196
    so √x = -196 – 126 + 368 = 46
    So, x = 2116
  5. 18% of 649.99 – 945 ÷ 16 + 456.23 = x
    A) 514

    B) 578

    A) 22
    B) 45
    C) 34
    D) 32
    E) 48
    View Answer
      Option C
    Solution:
    x% of 450 – 192 = 117 – 156
    x% of 450 = 153
    x = 34
  7. 58.09% of 1250 + 27.992% of 449.90 = x
    A) 845
    B) 715
    C) 890
    D) 765
    E) 850
    View Answer

    B) 35
    C) 64
    D) 60
    E) 63
    View Answer
      Option A
    Solution:
    x% of 4860 = 2565 + 459 – 351
    x% of 4860 = 2673
    x = 26730/486 = 55
  9. (23)2 – 24.069 × 15.992 + 15.99% of 550 = x
