Show Answer

Answer:

Correct Answer: C

Solution:

  • $ \because $ C.P. of first pipe $ =\frac{12\times 100}{(100+20)}=Rs.10 $

$ \Rightarrow $ C.P. of second pipe $ =\frac{12\times 100}{(100-20)}=Rs.15 $

$ \Rightarrow $ C.P. of both the pipes $ =10+15=Rs.25 $

$ \Rightarrow $ S.P. of both pipes $ =12+12=Rs.24 $

$ \therefore $ Loss on the whole $ =25-24=Rs.1 $
