    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

    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.
