Answer:
1) option: A (120 minutes)
2) option: A(96 minutes)
3) option: A
4) option: C
5) option: B
Step-by-step explanation:
Ques 1:
Let the total work be '240'
filling pipe empty pipe filling+empty pipe
Time 40 min 60 min x
Efficiency 240/40=6 240/60= -4 6-4=2
The efficiency of empty pipe is negative as it lead to more time in filling.
Hence the time taken by both the pipe will be =120 minutes.
Hence, option A is correct.
Ques 2:
Let the total work be '960'
Annmarie Gladys Annmarie+Gladys
Time 240 min 160 min x
Efficiency 960/240=4 960/160=6 6+4=10
Hence, the time taken if they work together is:
Hence, option A is correct.
Ques 3:
Let the total work be '1'
Brody Hudson Brody+Hudson
Time 3 min x min 5 min
Efficiency 1/3 -1/x 1/5
the efficiency of Hudson is negative as he is taking out the candies.
since, efficiency of Brody+efficiency of hudson= efficiency of both
that means
Hence, option A is correct.
Ques 4:
Let the total work be '60'.
Leanne Karl Leanne+Karl
Time 30 min 20 min x
Efficiency 2 3 5
Hence, the time taken by both of them is:
Hence, option C is correct.
Ques 5:
Let the total work be '1'
Genna Claude Genna+Claude
Time 4 hrs 3 hrs x hrs
Efficiency 1/4 1/3 1/x
Since, efficiency of Genna+Efficiency of Claude=Efficiency of both
that means
Hence, option B is correct.
Oy= (x + 7) (x - 2)
Oy= (x - 5)(x – 14).
Oy= (x + 5) (x + 14)
