1a. The amount of loan=$25,000
Simple interest rate=21%
Tin×=3 years
Simple interest =P×T×R/100
=25,000×5×21
=15,750
Amount payable=(25,000+15,750)
=$40.750
If he pay up everyday for 2 years amount paid each year=$40,750/2
=$20,375

1b. Let the member be represented by x,x+1
Smaller member = 3x
Large number=2 (x+1)
=2x+2
The sum=3x+2x+2=17
5x+2=17
5x=17-2
5x=15
x=15/5
x=3
% of the smaller number=3/17×100
=300/17
=17.7%
