Answer 1

Answer:

=cp of 14 copy is 240

=cp of 1 copy is 240÷14

=17.1428571

=sp of 10 copy is 160

= sp of 1 copy is 160÷10

=16

therefore he loss = 17.1428571 -16

=1.1428571

loss %= 100+loss ÷ 100 × cpt

= 100+1.1428571 ÷100x

Answer 2

Step-by-step explanation:

Cost of 14 copies is Rs 240

Cost of 1 copy =Rs 240/14 = Rs 120/7 =Rs 17.14

CP = Rs 17.14

Cost of 10 copies is Rs 160

Cost of 1 copy = Rs 160/10 = Rs 16

SP = Rs 16

Loss = CP - SP

= Rs (17.14-16)

= Rs 1.14

Therefore, loss percentage = (Loss/CP × 100)%

= (1.14/17.14×100)%

= (114/1714×100)%

= 6.65%
