• B. 7 : 13
• C. 32 : 39
• D. Inadequate data
• E. None of these

Answer 1

The correct option is C 32 : 39

Train A
Total passengers $=700$
General coaches $=700\times \frac{20}{100}=140$
AC coaches $=\frac{700}{4}=175$
Sleeper class $=700\times \frac{23}{100}=161$
First class $=700-(140+175+161)=224$
Train B
Total passengers $=700\times \frac{130}{100}=910$
AC coaches $=480-175=305$
Sleeper class $=910\times \frac{30}{100}=273$
First class $=910\times \frac{10}{100}=91$
General coaches $=910-(305+273+91)=241$
Required ratio $=224:273=32:39$
