Question

3rd and 4th question please

Answer 1

Answer:

3600 and 350

Step-by-step explanation:

3. first we will find LCM of 8,9,10

LCM is 360

but it is not a perfect square

so we will make it a perfect square

360 = 2*2*2*3*3*5 we will multiply it by 2 and 5 so that it can be 2^2*3^2*2^2*5^2=(2*2*3*5)^2= 60 ^ 2

so the smallest square number which is exactly divisible by 8,9,10 is 60 ^2 = 3600

4. total students = total rupees = 122500

let the values be X

X * X = 122500

X ^2 = 122500

X = √122500

X = 350
