29. 3. The water level in a container is 2.0 m on
Sunday. The water level drops by 25 % on
Monday. It rises by 40% on Tuesday as
compared to Monday’s level. What is the
height, in m, of the water level on
Tuesday?
A 0.9
B 1.2
C 1.9
D 2.1

30. Sunday = 2.0m
Monday = 2.0 – (25% × 2.0)
= 2.0 – 0.5
= 1.5
Tuesday = 1.5 + (40% × 1.5)
= 1.5 + 0.6
= 2.1

i) A locus must be drawn in a full line.
Do not draw dotted line.
ii) If the locus is a straight line, use a
ruler to draw.
iii) If the locus is a circle or part of a
circle, use a pair of compasses to
draw.

180. The allegory of the Frog ...
Lesson of Life N. 1
Once upon a time there was a race ...
of frogs

181. The goal was to reach the top of a high tower.
Many people gathered to see and support them.

182. The race began.

183. In reality, the people probably didn’t
believe that it was possible that the frogs
reached the top of the tower, and all the
phrases that one could hear were of this
kind :
"What pain !!!
They’ll never make it!"

184. The frogs began to resign,
except for one who kept on climbing
The people continued :
"... What pain !!! They’ll never make it!..."

185. And the frogs admitted defeat,
except for the frog who continued to insist.
At the end, all the frogs quit, except the
one who, alone and with and enormous
effort, reached the top of the tower.
The others wanted to know how did he
do it.

186. And discovered that he...
was deaf!
...Never listen to people who have the
bad habit of being negative...
because they steal the best aspirations
of your heart!

187. Always remind yourself of the power of the
words that we hear or read.
That’s why, you always have to think
positive
POSITIVE !!!!
Conclusion:
Always be deaf to someone who tells
you that you can’t and won’t achieve
your goals or make come true your
dreams.
