A) 15
B) 20
C) 30
D) 40
Correct Answer: C
Solution :
[c] Let the total goods be 100. Then, \[\frac{2}{5}\] of 100 were sold at 20% loss and \[\frac{3}{5}\] of 100 were sold at x % profit. Then, according to the question, 80% of\[~40+x%\] of 60 = 110% of 100 \[\Rightarrow \] \[\frac{80\times 40}{100}+\frac{x\times 60}{100}=\frac{110\times 100}{100}\] \[\therefore \] \[x=\frac{78\times 10}{6}=130\] \[\therefore \] Required profit percentage \[=130-100=30%\] |
