A mother has three sick children. She has a 24-ounce bottle of medicine and needs to give each child eight ounces of the medicine. She is unable to get to the store and has only three clean containers, which measure 5, 11 and 13 ounces. The electricity is out and she has no way of heating water to wash the containers and doesn’t want to spread germs. How can she divide the medicine to give each child an equal portion without having any two children drink from the same container?
Answer: Fill the 5 oz. and 11 oz. Containers from the 24 oz. container. This leaves 8 oz. in the 24 oz. bottle. Next empty the 11 oz. bottle by pouring the contents into the 13 oz. bottle. Fill the 13 oz. bottle from the 5 oz. container (with 2 oz.) and put the remaining 3 oz. in the 11 oz. bottle. This leaves the 5 oz. container empty. Now pour 5 oz. from the 13 oz. bottle into the 5 oz. bottle leaving 8 oz. in the 13 oz. bottle. Finally pour the 5 oz. bottle contents into the 11 oz. bottle giving 8 oz. in this container.

if 2+9=711 then find 12+3=??? number Puzzle with answer
Answer: 915
Solution:
if you look at the question we have equations as
2+9=711
14+6=820;
17+11=628
then 12+3=??
from Equation 1
2+9=711
2+9=(2-9)(2+9)
= 711
here we used a formula called a+b=(a-b)(a+b)
similarly for remaining equations
Equation:2
14+6=(14-6)(14+6)=820
Equation:3
17+11=(17-11)(17+11)=628
now we have 12+3=??
12+3=(12-3)(12+3)=915
12+3=915 is the correct answer
