Four of the following five are alike in a certain way and so form a group. Which is the one that does not belong to that group?
C - 2 = A, A + 3 = D F - 2 = D, D + 3 = G D - 2 = B, B + 3 = E I - 2 = G, G + 3 = J L - 2 = J, J + 3 = M
When a number is added to its multiple of 5 and its square, the sum of these three numbers is 91. Find the number.
If + means ÷, - means x, x means +, ÷ means –, Find the value for 72 + 8 – 5 × 18 ÷ 5.
If 84 × 13 = 8, 37 × 13 = 6, 26 × 11 = 6, then 56 × 22 = ?
