Step-by-step explanation:

sp=cp(1-l%)

= cp(1-8%) = cp(1-.08)

sp =0.92cp --- A

I guess its 10% less, instead of "loss"

cp1 = cp(1-10%) = cp(1-0.1) = 0.9cp

sp1 = sp+176

sp1 = cp1(1+20%) =0.9cp(1+0.2) = 0.9×1.2cp = 1.08cp

sp+176 = 1.08cp

substitute from A

0.92cp +176 = 1.08cp

176 = 1.08cp - 0.92cp = 0.16 cp

cp = 176/0.16 = 1100
