2. CONCEPT USED: ARITHMETIC
PROGRESSION
Avika and Dakshita visits a
temple in Arunachal Pradesh,
avika jumps 1 stair of 10cm,
dakshita jumps (2 stairs), avika
then jumps 3 stairs. Find how
much cms will dakshita jump
next?
0
•
A.P. = a+(n-1)d
=10+(4-1)10
= 40cm
Therefore, dakshita will jump 40cm
3. CONCEPT USED: PROBABILITY
Avika and Hemanshi visits a beach and
goes for a swim. Suddenly a high tide
came and one of them slipped and fell
down. The probability that it was Avika
is?
• Total outcomes= 2 girls
• P(E)= no. of favourable outcomes
• Total no. of outcomes
• =1
• 2
4. CONCEPT USED: VOLUME
The picture depictsthe famous
“Buddhist wheel” in arunachal
Pradesh. One can calculate
volume by the following steps:
• Volume of cylinder= πR2h
• 3.14x13x13
• =4116.54 cm2
5. CONCEPT USED: HEIGHT AND DISTANCES
This picture shows a famous
Shiva Linga of Arunachal
Praadesh. We need to find the
distance between observer and
top of shivling
TanA0 = Perpendicular
Base
A= 30
1/ 𝟑 = 7.5/ base
Base= 7.5 3
Therefore, the distance is 7.5 3cm
6. CONCEPT USED: HEIGHT AND DISTANCES
Picture shows a Buddha Murti.
The observer observes the
temple with 60 degree. He
observed bottom at 30 degree.
Find the height of statue
• SinA= P/H
• ½=P/12
• P=6cm
• Total height = 6+12= 18 cmz
7. CONCEPT USED: PROBABILITY
More than half of the fields in AP are
Bamboo’s. Lets calculate the volume of
it.
• Volume of Bamboo= πR2h
• =3,14 x 2 x 2 x 10
• =125.6 cm3
• So, volume of all 3 rrings of bamboo
• = 125.6 x 3
• =376.8 cm3
