Answer 1

Answer:

16%

Step-by-step explanation:

Given, 240×(x+10)%=180×x%+(180×x%)60%

240×(x+10)%=180×x%(1+60%)

240×(x%+10%)=180x%(160%)

240x%+24=(180x%)160%

240x%+24=288x%

48x%=24

x%=2448=0.5=50%

Check, 240(50+10)%=180×50%+(180×50%)60%

144=144

Next, (x+20)15%=(50+20)15%=70×15%=10.5

25%x=12.5

less % is 100%−10.512.5=100%−10.5×812.5×8=100%−84%=16%
