Question

11. Find the smallest square number which is completely divisible by each of the numbers 10,16 and 24.
12. The children of class VIII of a school contributed * 3025 for the Prime Minister's National Relief Fund,
contributing as much money as there are children in the class. How many children are there in the class?​

Answer 1

Answer:

11. 3600, 12. 55 children

Step-by-step explanation:

11. Prime factors of given numbers:

10=2*5

16=2*2*2*2

24=2*2*2*3

LCM(10,16,24)=2^4*3*5

We will get the smallest square divisible by all 3 numbers by adding a factor of 3*5 to make it a square of 4*3*5 which is 60^2=3600

12. Contribution= number of children= x

and x*x=3025

x^2=3025

x=√3025=55

Answer is 55 children
