By doing some calculation, 2+3=18, 3+5=42, 6+2=48 and find 5+6=??
A)74 B)70 C)72 D)76

• Ans is C)72
  Given 2+3=18==> (2^2+3^2)+(2+3)=18
  3+5=42==> (3^2+5^2)+(3+5)=42
  6+2=48==> (6^2+2^2)+(6+2)=48
  So 5+6=72==> (5^2+6^2)+(5+6)=72

• C)72
  
  (3+5)+(6+2)-(2+3)= 48+42-18 = 72

• it is looking like a + b = (a)^2+(b)^2+a+b;
  
  hence
  
  5 + 6 = 5^2 + 6^2 + 5 + 6 = 25 + 36 + 11 = 72
