Capacity of 1stTank =60 litres.
Amount of oil used by Sam=40% of 60 litres.
=(40/100)*60 litres.
=24 litres.
Amount of oil left = (60 - 24) litres
= 36 litres.
Acc. to Question, Amount of oil that was left, was poured in 2nd tank with capacity 40 litres.
Now,
Percentage of oil in 2nd tank=(36/40)*100 %
= 90 %. (1st Part Answer)
Now if 3 litres of oil is being used daily,
Amount of oil used in 10 days = (3*10)=30 litres.
Amount of oil left in the tank = (36-30) = 6 litres.
Now percentage of oil in tank = (6/40)*100 %
=15%
∴Percentage of oil left in tank = (100 - 15)% = 85% (2nd Part Answer)

quantity of oil in 1st tank = 60 litre
oil used = 40 % of 60
0.4 × 60 = 24 litre
rest oil = total quantity - oil used
= 60 - 24 = 36 litre
In 40 litre tank:
----------------------
quantity of oil = 36 litre
1 days consumption = 3 litre
10 days' consumption
= 3 × 10 = 30 litre
oil used in 10 days
= (30 × 100)/ 36 = 83.33 %
oil used in 10 days = 83.33%
Answer:
-------------
oil used in 10 days = 83.33%
-------------------------------------------------------
oil used = 40 % of 60
0.4 × 60 = 24 litre
rest oil = total quantity - oil used
= 60 - 24 = 36 litre
In 40 litre tank:
----------------------
quantity of oil = 36 litre
1 days consumption = 3 litre
10 days' consumption
= 3 × 10 = 30 litre
oil used in 10 days
= (30 × 100)/ 36 = 83.33 %
oil used in 10 days = 83.33%
Answer:
-------------
oil used in 10 days = 83.33%
-------------------------------------------------------
