If;
A x 4 = E
B / 4 = E
C + 4 = E
D – 4 = E
A + B + C + D = 100
Then;
E = ?
E = 16 . A = 0.25E and B = 4E B = 4E = 16 * 0.25E = 16A . C = E-4 and D = E+4 C+D = E-4 + E+4 = 2E = 8 * 0.25E = 8A . A+B+C+D = 100 A * (1+16+8) = 25A = 100 . A = 4 E = 4 * 4 = 16
If A x 4 = E B ÷ 4 = E C + 4 = E D - 4 = E A + B + C + D = 100
Challenge What is the value of E ?
If a/b = 51/54; c/d = 440/493; b/c = 29/32; e/f = 493/608; and d/e = 38/55 then what is the value of (abc/def)*17 = ?
If a/b = 21/34; b/c = 121/120; c/d = 17/77; e/f = 11/15 and d/e = 14/17 then what is the value of (abc/def)*2?
