Since the question directly mentions the sorting algorithm name that is merge sort and we can use a modified merge sort that returns the number of inversions of an array A[1 ∶ N] in O(N log N) time. Reference. → Cormen(3rd ed.), Chap-2, Page no-42 The key idea is to use the array index to find the number of inversions(as we know that while finding inversions two things (1: i < j, 2: A[i] >A[j] ) are of prime importance.) we use the fact that if we replace an element by its position in the same sorted array, the inverse count will remain the… [...]

let x = amount for he bought + amount spent on repair x--->[x+(20%of x)=1.2x]--->[1.2x-(10% of 1.2x)=1.08x]--->[1.08x+(10%of1.08x)] Given in question 1.08x+(10% of 1.08x)=1188 from this x=1000 you get Required answer = 1000 – 110 = 890. Therefore answer is option D [...]

Part filled in $1 $ minute: $\frac{1}{10}+\frac{1}{30}=\frac{2}{15}$ Part filled in $5 $ minute: $\frac{2}{15}\times 5=\frac{2}{3}$ Unfilled part= $1-\frac{2}{3}=\frac{1}{3}$ so this is filled by tape first by alone,hence will be filled in $30\times \frac{1}{3}=10$ minute. So option (C) is correct. [...]
