Answer : Option B
Explanation :
A : B = 100 : 90.
A : C = 100 : 72.
B : C = \( \frac { B } {A }\) X \( \frac { A } {C }\) =\( \frac { 90 } {100 }\) X \( \frac { 100 } {72 }\)=\( \frac { 90 } {72 }\)
When B runs 90 m, C runs 72 m.
When B runs 90 m, C runs 72 m[\( \frac { 72 } {90 }\) x 100] m = 80 m
B can give C 20 m.
