Question

To a sugar solution of 3 litres con-
taining 40% sugar, one litre of
water is added. The percentage
of sugar in the new solution is:​

Answer 1

Answer:

Step-by-step explanation:

40% of 3litres is 1.2litres

So, x%of x= 3litres+1litres

On solving, we get the concentration of sugar solution as 20%

Answer 2

sugar = 40/100 * 3 = 120/100 = 1.2 liters

percentage of new sugar 

= 1.2/(3+1) * 100%

= 1.2/4 * 100%

= 0.3 * 100%

= 30%
