'A + B' means 'A is brother of B'
'A – B' means 'A is mother of B'
'A × B' means 'A is husband of B'
'A ÷ B' means 'A is sister of B'
If C ÷ B – E + A × F – D, then which of the following statements is NOT correct?
26.23 × 31.82 + 44.8% of 1200 + ? = 1520
(899.117 + 1.1121) X 72.731 = ? + 49.95 X 64.78 + 29.50
(67.2)2 – (8.9)2 – (22.02)2 =?
(91.004)2 - (40.003)2 - (52.9)2 = ?
9.99% of 19.86% of 30.23% of (11999.84 × 9.68) = ?
63.89% of 549.68 – (739.87 ÷ 5.34) = ? × 11.89
23.95% of 274.99 - 34.99% of 120.01 = 19.95% of ?
