By selling some cloth at the cost price a merchant still gained 191/21%. How much less cloth does he measure for a meter?
1) 15 cm
2) 16 cm
3) 20 cm
4) None of these
Answer: 2
EXP:
Profit % = 19 1/21 => 1.19047.
Let he measure x cm for 100 cm. Then, 100/x = 1.19047 => x=84 cm
So he measures 16 cm less for every meter.
