C. Leena bought 2 saris for Rs 200 each and embroidery materials for Rs . 100. She embroidered both the saris identically. She sold one sari for a profit of Rs 100 and the other sari for a loss of Rs 50. What was the SP of each sari?
Answers
a.Cost Price of the rice=20×50=Rs.1000
Selling price=profit +cost price=400+1000=1400
b.cost of 1 metre=Rs.60
loss on 1 metre= Rs 10
Selling price of 1 metre=cost-loss=60-10=Rs.50
Selling price of 100 metres=50×100=5000
c.Sari 1
cost of sari=Rs.200
cost of embroidery=Rs.50
cost price=200+50=Rs.250
profit=Rs.100
Selling price=250+100=350
Sari 2
cost price of sari 2 will be same as sari 1 i.e.Rs.250
Loss=Rs.50
Selling price=250-50=200
Step-by-step explanation:
a. CP of rice per sack = ₹20
CP of 50 sacks of rice = ₹(20x50)
= ₹1000
Gain = ₹400
SP = CP of 50 sacks of rice + Gain
1000 + 400
₹ 1400
b. CP of cloth per meter = ₹60
Loss = ₹10
SP = 50 X 1000
₹50000
c. CP of 2 saris = ₹200
CP of 1 sari = ₹100
Gain on 1st sari = ₹100
Loss on 2nd sari = ₹50
SP of 1st sari = gain + CP
= ₹200
SP of 2nd sari = loss - CP
= ₹ 50
