Answer»

As we know, a cone with RADIUSR’ and height ‘h’, has a volume = 1/3 πr2h

Total volume of liquid = volume of FIRST conical vessel = (1/3) × (22/7) × (7)2 × 30 = 1540 cm3

Volume of liquid poured in one vessel = volume of second conical vessel

= (1/3) × (22/7) × (5)2 × 21 = 550 cm3

Total number of vessels filled = 1540/550 = 2.8

Hence, the third vessel is only filled = 0.8 = 80%

∴ The LAST vessel remained empty by = 100 – 80 = 20% = 1/5
