Question 134
A tap drips at a rate of one drop/sec. 600 drops make 100m1. The number of litres wasted in 300 days is
Solution
Rate at which tap drips = 1 drop/sec
Now, no. of seconds in 1 day = 24*60*60 = 86400 sec
=> In 1 day the tap drips 86400 drops
=> $$\frac{86400}{600} * 100$$ = 14400 ml = 14.4 litres
Thus, in 300 days, water wasted = 14.4*300 = 4320 litres
