Step-by-step explanation:
Total petrol brought=10 litres
Petrol used= Petrol used in car+ Petrol used in scooter = 5/1/2+3/2/9
( solving mixed fraction)
=11/2+29/9
Taking LCM of 9 and 2 i.e. 18
=11*9/18+29*2/9
=99/18+58/18
=99+58/18
=15/18
=8.72 litres of petrol left

Answer:
a man bought = 10 litre petrol
he used in car = 11\2 litre petrol
and then again used in scooter = 29\9
there for left petrol = total petrol - used petrol
=10-(11\2+29\9)
= 10-157\18
= 10 -8.72
= 1.28
