let x, y and z be the number of scholarship of 1250; 2500 and 4000
we have y =2z and x= 3y and 37500 = 1250x.

so x= 37500/1250 = 30, hence y=10 and z = 5

so answer A

ans is A.

total no. of $1250 scholarship = (37500/1250)=30
now, there are 3 times as many $1250 schol as $2500 schol
therefore, no. of $1250 scholarship = 3(no. of $2500 scholarship )
so no of $2500 schol = 10.
now there are twice as many $2500 scholarship as $4000 scholarship.
therefore,
no. of $2500 scholarship = 2(no. of $4000 scholarship )
10 = 2 (no. of $4000 scholarship )
hence , (no. of $4000 scholarship ) = 10/2=5
