Question

A man bought a bicycle for Rs. 1920 and sold it next year for Rs. 1440. Find the loss percent on his outlay.
​

Answer 1

Loss =1920-1440
=480
So, loss %= 480/1920.100
= 25%

Answer 2

Answer:

Solution:-

Tap A can fill 1 tank in 8 hours

Tap A fills in 1 hour = 1/8 tank

Tap B can empty 1 tank in 12 hours

Tap B empties in 1 hour = 1/12 hours

Both taps will fill in 1 hour = (1/8 – 1/12) tank

= 3 – 2/24

= 1/24

Hence, the tank will be filled completely in 24 hours .
