Answer:
no. of pen sells=45
therefore profit = 45×1=45rs.
loss on x pencil = x ×.40=0.40x rs.
a/q. = 0.40x-45rs=5
0.40x = 50rs
x=50/0.40
=125
OR
k so
Shopkeeper earns by pen =rs 1
no . of pens =45=45*1 =45
shopkeeper loses by selling pencils =40 paise
shopkeeper sells =40*5=200
200-45=155÷5 31 are the pencils he sold
