1 - 1/3 - 1/4 - 1/4 = 1/6

so, 72000 is 1/6 of the total.
The total is thus 432,000

1/3 = 144,000
1/4 = 108,000

You can massage the answer to the required format.

Thanks. I figuired out the working, but not sure how to use the Let statement. Would it be correct to say

Let A = original scholarship amount
A = 1-1/3 -1/4-1/4 x72,000
A = 1/6 x 72 = 432,000

Better would be

(1 - 1/3 - 1/4 - 1/4) A = 72000
1/6 A = 72000
A = 6*72000

or

A = 72000/(1 - 1/3 - 1/4 - 1/4)
