petrol(in litres) =34 litres,20 litres
It is a case of direct variation because here decrease in one quantity leads to decrease in another also.
510x20=yx34 (34 and510 get cut off by 17(17x2=34,17x30=510))
30x20=yx2 (2 goes in LHS)
30x20/2=y (2 and 20 get cut off because 2x10=20)
30x10=y
300=y
Therefore, y=300
the truck can cover 300Km in 20 litres
