Question

At the beginning of the first day, a granite quarry has 14 truckloads of granite ready for delivery. Every day, the quarry mines 8 truckloads of granite and delivers 6 truckloads. How many truckloads of granite does the quarry have on hand at the beginning of the sixth day? A. 50 B. 22 C. 62 D. 24

Answer 1

Truckloads at the beginning of first day =14

Truckloads mined on first day =8

Total truckload on first day = 8+14 = 22

Truckload delivered on first day = 6

Truckload at the end on first day = 22-6 = 16

Truckloads mined on second day =8

Total truckload on second day = 8+16 = 24

Truckload delivered on second day = 6

Truckload at the end on second day = 24-6 = 18

Truckloads mined on third day =8

Total truckload on third day = 8+18 = 26

Truckload delivered on third day = 6

Truckload at the end on third day = 26-6 = 20

Truckloads mined on fourth day =8

Total truckload on fourth day = 8+20 = 28

Truckload delivered on fourth day = 6

Truckload at the end on fourth day = 28-6 = 22

Truckloads mined on fifth day =8

Total truckload on fifth day = 8+22 = 30

Truckload delivered on fifth day = 6

Truckload at the end on fifth day = 30-6 = 24

So at the beginning of sixth day will be equal to what is at the end of fifth day.

Answer is 24 option D.
