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

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

If + means x, x means -, ÷ means +, - means ÷, then 175 - 25 ÷ 5 + 20 x 3 + 10 equals to:

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 + means ×, − means ÷, × means − and ÷ means +, find 15+8×4−2÷10.
