Answer:
3500
Step-by-step explanation:
A:B:C:D=2:7:11:12
let the ratio of A,B,C & D be 2x,7x,11x and 12x respectively
so total sum of money=2x+7x+11x+12x=32x
Ratio of B+Ratio of D=6650(given)
=7x+12x=6650
=19x=6650
x=6650/19
x=350
A=2x
=2*350=700
D=12x=12*350
=4200
the difference between A & D=4200-700
=3500.
