so,cost of 1earaser=250/100=2.5
sp of 25earaser=25×2.5=10
so,loss%=10/25×1/10×100
=4%
sp of 25earaser=25×2.5=10
so,loss%=10/25×1/10×100
=4%

c.p = 250
let s.p of 1 eraser =x
s.p of 25 eraser = 25x (=loss)
s.p of 100 eraser =100x
loss =c.p - sp
25x = 250-100x
x = ₹2
so s.p of 1 eraser = ₹2
s. p of 25 eraser = ₹50 (= loss)
loss% =( loss×100)÷ c.p
= (50x100)÷250
loss% = 20%
