60


Marks in Science- x
Marks in Hindi- y
1/3x=1/2y+30
x+y=240
y=?


x= 240-y--> 1/3x = 80-1/3y
80-1/3y=1/2y+30 --> 5/6y=50--> y=60

A science teacher told his after school class, "Whoever can get this egg into this smaller glass bottle will win no homework for a week! The rules are: the egg has to go into the bottle in one piece, and you can't break the bottle. You can also use anything in the science lab. So, do we have any volunteers?"

A boy raised his hand and the teacher pointed at him. The boy took the egg and looked around the science lab for the things he could use. He saw some writing paper, a pack of matches, some vinegar, a sink, and the glass bottle. By the end of the after school class, the boy had gotten the egg into the smaller bottle.

How did he do it?
