Taps A and B can fill a bucket in 15 minutes and 30 minutes respectively. If both are opened and A is closed after 4 minutes, how much further time would it take for B to fill the bucket? | [
"19 mins.",
"18 mins.",
"15 mins.",
"16 mins."
] | B | Explanation:
Part filled in 3 minutes =
4∗(1/15+1/30)=4∗1/10=2/5
Remaining part =1−2/5=3/5
=>1/30:3/5=1:X
