Answer:
9%
Step-by-step explanation:
Cost of 1/5 good = 1500*1/5= 300
Profit= 5%
SP = (profit+100)/100*CP
SP= (5+100)/100*300
SP = 105/100*300
SP= 1.05*300= 315
Cost of 4/5 good = 1500*4/5= 1200
Profit= 10%
SP= (profit+100)/100*CP
SP= (10+100)/100*1200
SP = 110/100*1200
SP= 1.10*1200= 1320
Total SP = 315+1320= 1635
Net profit= 1635-1500= 135
Profit% = 135/1500*100%
Profit% = 0.09*100%
Profit% = 9%

Answer:
a.) x = 5.36
b.) y = - 0.001
c.) t = 11.26
d.) k = 4.57
Step-by-step explanation:
a) x−1.27=4.09
b) 2.3−y=2.301
c) t+3.04=14.3
d) 1.1+k=5.67
Solving. right?
a.) x = 4.09 + 1.27 = 5.36
b.) y = 2.3 - 2.301 = - 0.001
c.) t = 14.3 - 3.04 = 11.26
d.) k = 5.67 - 1.1 = 4.57
