Question

Neha sold her old bicycle suffering a
loss of 6%. If she had sold her bicycle
for 90 more, she would have made a
profit of 3%. Find the cost price of the
bicycle.

​

Answer 1

Answer:

let the cost price be x and sp be y

loss % = cp - sp/ cp *100

6/100 = x-y/ x

6x =100x-100y

6x -100x=-100y

-94x=-100y

y=94x/100

3% profit=(y+90)-x/x

3/100=(y+90)-x/x

3x=100y +9000-100x

103x=100(94x/100)+9000

9x =9000

x =1000

hence cp =₹1000
