Question

A vessel full of water weighs 40 kg. If it is onethird
filled, its weight becomes 20kg. What is the
weight of the empty vessel?
(1) 10 kg (2) 15 kg
(3) 20 kg (4) 25 kg

Answer 1

Answer:

1) 10 KG IS CORRECT ANSWER

Explanation:

3 / 3 ( FULL WATER ) - 1 / 3 ( ONE THIRD OF VESSEL WITH WATER ) = 2 / 3

FULL WATER - 1/ 3 OF WATER

=} 40 - 20 = 20 KG

SO , 2 / 3 = 20

LET THE WEIGHT OF WATER BE X

A/Q,

=} 2 / 3 X = 20

=} X = 20 × 3 / 2

=} X = 60 / 2

=} X = 30 KG ( 60 GETS CANCELLED BY 2 RESULTING IN 30 )

SO, THE WIEGHT OF WATER IS X = 30 KG

THEREFORE,

THE WEIGHT OF VESSEL FULL OF WATER - WIEGHT OF WATER =

WIEGHT OF VESSEL

40 KG - 30 KG = 10 KG

SO , 1) 10 KG IS THE WIEGHT OF VESSEL
