Answer:
96
Step-by-step explanation:
its a simple problem
For the first 60 positive integers, a = 1, n = 60, l = 60.
Sn = n/2(a + l)
s = 60/2(1 + 60) = 30(61)
For the next 60 positive integer, a = 61, n = 60, l = 120
Sum = 60/2(61 + 120) = 30(61 + 120) = 30(61) + 30(120) = s + 3600
Sum of first 120 positive integers = s + s + 3600 = 2s + 3600
The solution to the problem is as follows:
<span>7(4)/4(4) = 28/16
28+16= 44
</span>
Therefore, the size of the graduating class would be 44 students in all.
I hope my answer has come to your help. God bless and have a nice day ahead!
