      Option C
    Solution: 

    3/7 × 1090 = 468
    405 ÷ 17 = 24
    17% of 465 = 79
  5. 20.95% of 410 – 86.03% of 235 = √x – 3000 ÷ 20.98
    A) 756
    B) 1089

    D) 729
    E) None of these
    View Answer
     Option D
    Solution:
    21% of 410 = 86
    86% of 235 = 202
    3000 ÷ 21  = 143
    So (86 – 202 + 143) = √x
  6. √(43% of 549 + 28% of 1550) = x
    A) 24 or -24
    B) 26 or -26
    C) 27 or -27
    D) 32 or -32
    E) None of these
    View Answer
     Option E
    Solution:

    43% of 549 = 236
    28% of 1550 = 434
    S0 √(236+434) = x
    So x = √676 = 26. Root does not give negative value.
