## Karnataka State Syllabus Class 6 Maths Chapter 3 Playing with Numbers Ex 3.7

Question 1.
Renu purchases two bags of fertiliser of weights 75 kg and 69 kg. Find the maximum value of weight which can measure the weight of the fertiliser exact number of times.
Solution:
Weight of the two bags = 75 kg and 69 kg
Maximum weight = HCF (75, 69)

75 = 3 × 5 × 3
69 = 3 × 23
HCF = 3
Hence, the maximum value of weight, which can measure the weight of the fertilizer exact number of times, is 3 kg

Question 2.
Three boys step off together from the same spot. Their steps measure 63 cm, 70 cm and 77 cm respectively. What is the minimum distance each should cover so that all can cover the distance in complete steps?
Solution:
Step measure of 1 Boy = 63 cm
Step measure of 2 Boy = 70 cm
Step measure of 3 Boy = 77 cm
LCM of 63, 70, 77

LCM = 2 × 3 × 3 × 5 × 7 × 11 = 6930
Hence, the minimum distance each should cover so that all can cover the distance in complete steps is 6930 cm.

Question 3.
The length, breadth and height of a room are 825 cm, 675 cm and 450 cm respectively. Find the longest tape which can measure the three dimensions of the room exactly.
Solution:
Length = 825 cm = 3 × 5 × 5 × 11
Breadth = 675 cm = 3 × 3 × 3 × 5 × 5
Height = 450 cm = 2 × 3 × 3 × 5 × 5
Longest tape = HCF of 825, 675, and 450 = 3 × 5 × 5 = 75 cm
Therefore, the longest tape is 75 cm.

The LCM of 15 and 20 is 60.

Question 4.
Determine the smallest 3-digit number which is exactly divisible by 6, 8 and 12
Solution:
Smallest number = LCM of 6, 8, 12

the smallest 3-digit multiple of 24.
It can be seen that 24 × 4 = 96 and 24 × 5 = 120.
Hence, the smallest 3-digit number which is exactly divisible by 6, 8, and 12 is 120

Question 5.
Determine the greatest 3-digit number exactly divisible by 8, 10 and 12.
Solution:
LCM of 8, 10, and 12
2, 8,10,12

LCM = 2 × 2 × 2 × 3 × 5 = 120
We have to and the greatest 3-digit multiple of 120.
It can be seen that 120 × 8 = 960 and 120 × 9 = 1080.
Hence, the greatest 3-digit number exactly divisible by 8, 10, and 12 is 960.

Question 6.
The traffic lights at three different road crossings change after every 48 seconds, 72 seconds and 108 seconds respectively. If they change simultaneously at 7 a.m., at what time will they change simultaneously again?
Solution:
Time period after which these lights will change = LCM of 48, 72, 108

LCM = 2 × 2 × 2 × 2 × 3 × 3 × 3 = 432
They will change together after every 432 seconds i.e., 7 min 12 seconds.
Hence, they will change simultaneously at 7 : 07 : 12 am.

Question 7.
Three tankers contain 403 litres, 434 litres and 465 litres of diesel respectively. Find the maximum capacity of a container that can measure the diesel of the three containers exact number of times.
Solution:
Maximum capacity of the required tanker = HCF of 403, 434, 465
403 = 13 × 31
434 = 2 × 7 × 31
465 = 3 × 5 × 31
HCF = 31
A container of capacity 31 l can measure the diesel of 3 containers exact number of times

Question 8.

Question 1.
What are the reasons for the decline of Harappan civilisation?
Harappan Civilization developed along the Indus river. The River Indus irrigated the agricultural lands of the inhabitants. Though agriculture flourished, River Indus flooded at regular intervals leading to huge loss of crops, grains and trade which consequently proved to be uneconomical. They migrated to other pleaces with suitable arable land.The cities of Indus Valley Civilization were well planned. They inhabitants built wide roads with wellplanned drainage system and even multistoreyed buildings.

Since agriculture flourished they store excess food grains in granaries. Since agriculture was labour intensive they had to build large quarters for the labour force and lifestocks like cattle, goats, pigs, cats, dogs, camels and donkeys. Even trade with other civilizations flourished. All this required huge quantities of burnt bricks to build the infrastructure. They used large quantity of fire¬wood to bum bricks, which eventually led to the destruction of forests. So they had to migrate to other places.

Although the Indus valley inhabitants gave importance to cleanliness and public-health. Trade with other civilizations brought new diseases which were infections, and which led to mass extinction of the inhabitants so they migrated to, other safe places in fear of death. Moreover, the invation by Aryans, destroyed their cities and they fled to other safe places in fear, abandoning their civilization.

They also used cosmetics and perfumes. They also played Marbles, balls and dice, as recreational sports. They also enjoyed to watch bull-fight, similar to us watching cricket or football. Even their children played with dolls made of clay and wood or metal.

The main occupation of Harappanas was agriculture and rearing domestic animals. They also carried trade with other civilizations. Just like us they were interested in art and architecture. They made clay idols of Mother Goddess. Beautiful artifacts like the copper figurine of a dancing girl and the head of a bearded man made of stone were found while excavating Harappan sites. Just like us they were religious people and worshipped Pashupati and performed fire-rituals. They also has a unique script which is yet to be deciphered.
