Question

A packet of sugar weighing 20g is added to salt water, making the ratio of the amount of sugar to salt in the solution is 2:3. Then 15g of salt is added. Find how much more sugar (in grams) should be added, so that the ratio of sugar to salt will become 4:5

Answer 1

Step-by-step explanation:

ANSWER

Mas of common salt (solute)=40 g

Mass of water (soluted) =320 g

mass of solution=320+40

=360 g
