Answer 2

Answer:

i) 125 erasers

ii) 45 pencils

Step-by-step explanation:

i) Sold 35 pencils i.e., 35 rs profit on pencils

but given overall loss as 10rs.. profit on pencils - overall loss = loss on erasers.

35-10 = 25rs as loss on erasers.

for 5 erasers the shopkeeper loses Rs 1.that means he must have sold 125 erasers to incur a loss of 25rs.

ii) overall Profit = 25.

Erasers sold = 100.

loss incured is 20rs.

proft on pencils = overall profit + erasers loss.

i.e., 45

45 pencils were sold.
