Question

the selling price of 10 pencil is equal to cost price of 11 pencils find the profit percent

Answer 1

Answer:

Step-by-step explanation:

Let C.P. of a pencil Rs. 1.

So C.P.of 11 pencils=Rs.11.

But S.P. of 10 pencils=Rs.11

Therefore 11–10=Rs.1 profit,

So profit%=1/10=100/10=10% .

Answer 2

HEY HERE IS YOUR ANSWER!!!!!
CP OF THE 11 PENCIL=?
CP OF 1 PENCIL=1/11

SP OF 10 PENCIL = ?
SP OF 1 PENCIL =1/10

THEREFORE, PROFIT OCCURED
PROFIT= SP - CP
=1/10-1/11
LCM OF 10,11
LCM =110
1/10×110(MULTIPLING BOTH SIDES)
11/110-10/110
1/110
SO THIS IS YOUR ONLY PROFIT
P%=P/CP ×100
=1/110÷1/11×100
=1/110×11/1×100
=ANSWER IS 10
