CTS Company Numerical Ability Ratio and Proportion

A rail network consist of 68 routes touching station A, B, C. 5 routes touches each of the three station. 2 routes touches B, C; 3 route touches B, A. 4 Route touches A, C. The ratio of route touching the A:B:C are 11:15:8. Find out how many route touches A, B, C, only. Find out also how many route touches A, B, C station?

Read Solution (Total 2)

Given ratio as A : B : C = 11:15:8
Total routes for A = 68(11/34)= 22
A only = 22-3-5-4=10
Similarly total routes for B= 68(15/34)=30
B only = 30-3-5-2=10
Total routes for C= 68(8/34)= 16
C only = 16-4-5-2= 5
Number of routes touches A B C Only = 10+20+5=35
All routes of A B C Is= 22+30+16= 68
