Find the value of x, if: 2 * 3 = 11, 3 * 5 = 23 and x * 6 = 41.

If ÷ means +, - means ÷, x means - and + means x, then the value of ((36x4)-8x4)/(4+8×2+16÷1) is

If 4 + 5 - 2 = 33 and 10 + 12 - 5 = 119, then 6 + 8 - 3 =

If a * b = ab + b - a, what is the value of c such that c * (2 * 5) = 97?

If 3 × 4 = 1609, 5 × 6 = 3625 and 1 × 2 = 401, then 4 × 7 equals:

If a ÷ b means 'a to be added to b' and a × b means 'a to be divided by b', then the value of (14 ÷ 7) ÷ (14 × 7) is
