Savatey [412]
You have to find the greatest number that divide 294, 252 and 210, i.e., the greatest common factor.

Then, you need to factor each number and calculate the product of the common factors raised to the lowest exponent.

294 = 2*3*7^2
252 = 2^2 * 3^2 * 7
210 = 2*3*5*7

Greatest common factor = 2*3*7 = 42

The biggest possible number of students to distribuute the balls equally is 42

a man deposits 45 into an account the next day he makes 3 deposits of 20 $ each a week later he withdraws 105$
zheka24 [161]

Answer:

The amount available in account at last is $0  

Step-by-step explanation:

Given as :

The withdrawal amount from the account at the end = $105

The first deposit amount = $45

The next three deposit amount = $20 each

I.e The second deposit amount = 3 × $20

Or, The second deposit amount = $60

Let The amount available in account at last = $A

<u>Now, According to question</u>

The amount available in account at last = (first deposit amount  + second deposit amount) - withdrawal amount from the account at the end

i.e A = ($45 + $60) - $105

Or, A = $105 - $105

∴  A = $0

So, The amount available in account at last = A = $0

Hence, The amount available in account at last is $0   . Answer
