detailed solution did not come fast. it takes long times

Question:

There was a leakage in the container of the refined oil. If 11 kg oil is leaked out per day then it would have lasted for 50 days, if the leakage was 15 kg per day, then it would have lasted for only 45 days. For how many days would the oil have lasted, if there was no leakage and it was completely used for eating purpose?

Options:
A) 80 days
B) 72 days 
C) 100 days
D) 120 days
Solution:
Ans: (b)

Let \(x\) kg of oil be used for the eating purpose, daily, then 
(\(x\)+11) \(\times\)50 = (\(x\)+15) \(\times\)45
→ \(x\) = 25
Thus, Total quantity of oil,
= (25 +11) \(\times\)50 
= 1800
Hence, required number of days,
=\(\cfrac{1800}{25}\) = 72 days.

Dear student,
Please read the solution properly,
In last step total quantity of oil has been divided with x (x= oil used for the eating purpose).
