Question

An empty flowerpot has a mass of 800g. The mass of the flowerpot increases to 4kg when filled with soil. A different flowerpot is 25% lighter but holds 40% more soil. Calculate the mass of this flowerpot when it is full of soil.

Answer 1

Step-by-step explanation:

SOLUTION

Mass of empty flowerpot is = 800g.

Mass of flowerpot filled with soil = 4kg.

Lighter flowerpot = 25% = 25/100.

In lighter flower 40% add more soil.

Now,

=> 25/100 × 800

=> 200g

=> 40/100 × 4000

=> 1600 g

=> 1600g - 200g

=> 1400g

Hence,

Mass of flower with full soil is 1400g
