loss per cent.​

Answer 1

Answer:

4%

hope it helps you..

Step-by-step explanation:

let s.p of one pen=₹1

total 12dozen pens

s. p. =12*12*1=144 loss =₹6

c. p. =s.p.+loss=144+6=₹150

loss %=loss*100/c.p.

=6*100/150

=4%

Answer 2

His  loss percent is 4%

Step-by-step explanation:

Let SP of 1 pen = Re.1

1 dozen = 12 pens

12 dozen pens = $12 \times 12 = 144 pens$

SP of 144 pens = Rs.144

S.P. of 6 pens = Rs.6

We are given that By selling 12 dozen pens, Raman lost an  amount equal to the S.P. of 6 pens.

Loss = Rs.6

CP = Sp+Loss

CP = Rs.144+Rs.6= Rs.150

$Loss\% = \frac{CP-SP}{CP} \times 100\\Loss\% = \frac{150-144}{150} \times 100$

Loss% = 4%

Hence his  loss per cent. is 4%
