15 Digits on a Clock Face
15= M on a D M C
d=3c
2+21=23 or 3+15=18 ok . ans:h-c-d-d-g-g 45+585*=474 552++
It is the formula for the circumference C of a circle where D is the diameter. C = (pi) D
The answer might depend on what c and d are supposed to be!
the answer is a
C = D C = 10 utils, and D = 10 utils
They all equal each other. a = b = c = d = e e = a e = b e = c e = d e = e
As A/B=C/D , So B=(A*D)/C
a+b+c+d+e = 30 (i) c+e = 14 (ii) d+b = 1 (iii) a = 2b-1 (iv) a+c = 10 (v) By (i)-(ii)-(iii): a = 15 then, by (iv): b = 8 and by (v): c = -5 Also, b = 8 so by (iii): d = -7 and then by (i), e = 19
c = 6 and d = 7
