4. At a certain school, the ratio of the number of 2nd graders to the number of 4th graders is 8 to 5; the ratio of the number of 1st graders to the number of 2nd graders is 3 to 4; and the ratio of the number of 3rd graders to the number of 4th graders is 3 to 2

In the table, select a value for the number of 1st graders and the number of 3rd graders, so that the two numbers are jointly consistent with the information provided. Make only two selections, one in each column.

------------------------------------ 4
------------------------------------ 8
------------------------------------ 12
------------------------------------ 14
------------------------------------ 15

a/b = 3/4.
b/d = 8/5
c/d= 3/2.
a/c = ??

a/c = a/b * b/d * d/c
= 3/4 * 8/5 * 2/3
a/c = 4/5 . .

So this satisfied by a= 12, and b = 15 . .

Hi,

Multiplying the ratios to get ratio of 1st graders: 3rd graders = 4:5.
This can be clearly seen for values 12:15.Hence 1st Graders = 12 & 3rd Graders = 15 out of the given set of values.

Thanks & Regards,
Prateek Sharma.
