Step-by-step explanation:
CP of 50 glasses is given 1500 so,
CP of one glass is 1550÷50 it mean the cost price of one glass is 30
now it have your question has said 4 glasses with broken so ,
1500-120
1380
he sold each glasses at the cp of 35 so,
46×35
1610
now,
profit =SP-CP
1610-1500
=110
Actual profit is 110 and profit percent =actual profit/CP ×100
110/1500×100
=7.3333%
