Answer 1

answer is16:15 pls mark it as brainliest answer if u like it

Answer 2

300=$\frac{x*3*5}{100}$+$\frac{(1550-x)*3*8}{100}$

300*100=15x+37,200-24x

30,000=15x+37,200-24x

24x-15x=37,200-30,000

9x=7,200

x=$\frac{7200}{9}$

x=800(for 8%)

1550-x=1550 - 800

1550-x=750(for 5%)

$\frac{800}{750}$=$\frac{16}{15}$=16:15

∴The ratio of money lent at 5% to that lent at 8% is 16:15
