Answer 1

Answer:

47 whole 2/5 litres

Step-by-step explanation:

Initial volume of oil = 30 whole 2/5 = 152/5 litres

Volume of oil filled = 37 whole 2/3 = 113/3 litres

Hence, total volume = 152/5 + 113/3 = 1021/15

Volume of oil pumped out = 20 whole 2/3 = 62/3 litres

Hence, volume of oil left in tank = 1021/15 - 62/3 = 711/15 litres = 237/5 = 47 whole 2/5 litres
