A water pipe is cut into two pieces. The longer piece is 70% of the length of the pipe. By how much percentage is the longer piece longer than the shorter piece?
-
- 140%
- 400/3%
- 40%
- None of these

Increase in percentage of longer pipe compared to shorter pipe
= [(70 - 30)/30] x 100%
= (40/30) x 100%
= 400/3 %
