HCF OF 20 30 and 40 by listing common factors :-

factors of 20 -  1,2,4,5,10,20

factors of 30 - 1,2,3,5,6,10,15,30

factors of 40 - 1,2,4,5,8,10,20,40

There are 4 common factors

i.e, 1,2,5 and 10

therefore,

the greatest common factor of 40,20 and 30 is 10

Answer:

∴ Greatest common factor of [tex]40,20[/tex] and [tex]30[/tex] is [tex]10[/tex].

Step-by-step explanation:

• In context with question asked,
• We have to find the greatest common factor of [tex]40,20[/tex] and [tex]30[/tex].
• To find greatest common factor, we have to first find factors of given numbers.
• So, the factors are,

       Factors of [tex]40=1,2,4,5,8,10,20,40[/tex]

       Factors of [tex]20=1,2,4,5,10,20[/tex]

       Factors of [tex]30=1,2,3,5,6,10,15,30[/tex]

• We can see that, the greatest common factor is [tex]10[/tex].
• ∴ Greatest common factor of [tex]40,20[/tex] and [tex]30[/tex] is [tex]10[/tex].

• The growth of microorganisms especially bacteria is the commonest reason for the spoilage of achars and pickles.
• When we add salt to the achars and pickles, their substance concentration will increase as compared to the inner surroundings of the microorganisms.
• Due to the hypertonic surrounding provided to the microorganisms, osmosis happens.
• In osmosis water moves from the internal hypotonic surrounding of the microbes to the external hypertonic surrounding inflicting the microbes to dehydrate that eventually results in their death.
• Thus salt or sodium chloride is employed for the preservation of achars and pickles.

Workers Day celebration.

A workers day celebration was organised in our school campus on January 9,2018. The students of almost all the classes have participated in it.

Including our respective principal, teachers and staff

thanks

Explanation:

Every year all over the world, 1st May is celebrated as International Worker's Day, and we at St. Joseph's School celebrate it with no less spirit. All efforts are made to show our gratitude in an interesting way. Students gathered in the school ground, sharp at 7:30 AM before the arrival of the school staff. Everyone made a effort to show how they are thankful and grateful to have the staff members in their life. The school was cleaned by the students under teacher's supervision. All the staff members were greeted at the main gate of the School at 8:00 AM with a hand-made card, and then initiated the cultural activities with blessings from the oldest and wisest staff, Mr. Raju. The highlight of the programme was the principal's speech who emphasized on the help he got to run the school from all and how each one of them inspire him to work hard to take the institution to new heights. The sweets and gifts were also distributed at the end of the program. The day at school ended on a sweet note to meet the next day with same energy and love.
