Efficiency of Kanchan is four times to that of
Hina. If they will complete the work is 24
days by working together, then in how many
days can Hina alone complete the work ?
(a) 36 days
(b) 24 days
(c) 144 days
(d) 96 days
Answers
Answer:
Hina can complete the work in 120 days which is not in the given option.
Step-by-step explanation:
We have given efficiency of Kanchan is 4 times as that of Hina
Let the work done by Hina in one day is 1
Then work done by Kanchan in 1 day = 4
So total work done by both in one day = 4+1 = 5 work
As they can together complete the work in 24 days
So total work = 24×5 = 120 work
As in one day Hina does 1 work
So time taken by Hina to complete 120 work = 120 days

(d) 84 days.
Question:-
- Efficiency of Kanchan is four times to that of Hina. If they will complete the work is 24 days by working together, then in how many days can Hina alone complete the work ?
- (a) 36 days
- (b) 24 days
- (c) 144 days
- (d) 96 days
To find:-
- Number of days hina will take to complete the work alone.
Solution:-
We have given efficiency of Kanchan is 4 times as that of Hina
Let the work done by Hina in one day is 1
Then work done by Kanchan in 1 day = 4
So total work done by both in one day = 4+1 = 5 work
As they can together complete the work in 24 days
So total work = 24×5 = 120 work
As in one day Hina does 1 work
So time taken by Hina to complete 120 work = 120/1 = 120 days
Answer:-
- Hina can complete the work in 120 days which is not in the given option.
