Question

a tea merchant sells the tea at a loss of 6 % but uses a weight of 1800 g instead of 2 kg. nd his actual gain percent.

Answer 1

lET COST PRICE OF 1 KG BE P.
CP = 0.84P
SP= 0.96P
GAIN= 0.12P
GAIN%= 0.12P*100/0.84P=14.2%

Answer 2

let cp of 1 kg =100
cp of 1800g=180
loss=6%
so loss for selling 2000g
6%=loss/200×100
loss=12
hence sp of 1800g= 188
now profit%=8/180×100. (since188-180=8)
profit%= 4.45%(approx)
