The ABO blood group system is widely credited to have been discovered by the Austrian scientist Karl Landsteiner, who identified the O, A, and B blood types in 1900. Landsteiner originally described the O blood type as type "C", and in parts of Europe it is rendered as "0" (zero), signifying the lack of A or B antigen. Landsteiner was awarded the Nobel Prize in Physiology or Medicine in 1930 for his work. Alfred von Decastello and Adriano Sturli discovered the fourth type, AB, in 1902.
136.02 + 80.004 - 9.892 + {(30.02)2 /(15.02 × 1.98)} of 18.22% = ?
1111.25 × 9.05 + 2323.23 × 9.05 – 2121.37 × 9.05 = ?
20.22% of (61.9 × 5.01) + 69.97 =?
What approximate value will come in place of the question mark (?) in the following question? (Note: You are not expected to calculate the exact value.)...
44.98% of 399.98 = ? x 19.98 - (39.98% of 2499.98)
2720.03 ÷ 79.98 x 39.9 = ? + 40.32
125.9% ÷ 9.05 x 99.98 = ? - 69.97 × √324.02 ÷ 5.98
23.87% of 449.86 + 17.83 of 4.09 = ?
