=Rs.1.06

S.P. of 11 apples=Rs.12

11

12

=Rs.1.09

∴ C.P. of 11 apples=Rs.1.06×11

C.P.=Rs.11.66

Answer 2

Answer:

Loss % = 11%

Step-by-step explanation:

Given that

boy buys 8 apples for Rs 9.80.

Lets the number of apples he buy = 88

Now find Cost Price for 88 apples,

Total Cost Price ( C.P ) = ( 88 )( 9.8/8 )

=> C.P = (11)(9.8)

=> C.P = 107.8 Rs.

Total C.P = Rs.107.8

also given that,

boy sells them at 11 for Rs 12,

Now find selling price for 88 apples,

Selling Price ( S.P ) = 88( 12/11 )

=> S.P = 8(12)

=> S.P = 96

Selling Price = Rs.96

We see that boy getting loss,so

loss = C.P - S.P

=> loss = 107.8 - 96

=> loss = 11.8

Loss = Rs.11.8

Therefore, Loss% = ( loss )( 100 )/C.P

=> loss% = ( 11.8 )( 100 )/107.8

=> loss% = 10.9% = 11% apprx.

Therefore, Loss% = 11%
