Question

A student by 3 pencil is for rupees 4 and sells all at 4 for rupees 5 his gain or loss percent is

Answer 1

here is the solution...

Cost Price

price of 3 pencils are 4 Rs
therefore, price of 1 pencil is 4/3 Rs

Sale Price

price of 4 pencil is 5 Rs
therefore, price of 1 pencil is 5/4 Rs

since CP<SP

therefore,

loss
=CP-SP
=4/3-5/4
=1/12

THEREFORE,
loss% = loss/CP × 100
= 1/12 ÷ 4/3 ×100
=1/12×3/4×100
=25/4
=6.25 % (ANS)
