Help Ramu Problem

sir i am not able to understand the problem

1.)2

2.)1 3 7 19

3.)2 3

4.)2 5

5.)4 4 4

6.)4 3 2 1

7.)1 3

8.)798

9.)1 2 3

sir in this input file line number 1 says the number of iteration

line 2->1 3 7 19 gives cost of c1,c2,c3,c4

line 3->2 3 tells the number of rickshaws and cabs ramu will use

but line 4->2 5 what does here 2 and 5 represnts

and line 5->4 4 4 here what does 4 4 4 represents???

The fourth line contains n integers ai (0 ≤ ai ≤ 1000) — the number of times Ramu is going to use the rickshaw number i.
The fifth line contains m integers bi (0 ≤ bi ≤ 1000) — the number of times Ramu is going to use the cab number i.

Sir then I 5th if it contains numver of times ramu uses cans than in 5th line there is 4 that means ramu will use 4th can but there are only 3 cabs available and why is there three times four???in 5th line??
