Answer 1

Answer:

Step-by-step explanation:

Amrutha bought 20 pens and 10 pencils for 150 Rupees.  

Sold 60% of the pens and 80% pencils,

Pens Sold for rupees 10 each

Pencil was sold at a profit of 10% and each pencil by 50 Paisa over cost

the remaining pens and pencils could not be sold

To Find : what is Amruta overall profit or loss​

Solution :

Total Cost Price = Rs 150

Pen Cost = A  Rs

Pencil Cost = B   Rs

20A + 10B = 150

=> 2A + B = 15

pencil was sold at a profit of 10% and each pencil by 50 Paisa over cost

=> Pencil Sold at  B + (10/100)B = 1.1B  = B + 50/100

=> 0.1B = 50/100

=> B = 5

2A + B = 15 => A = 5

A = 5 and B = 5

60 % of Pen  = (60/100)20 = 12

Pen sold at  Rs 10 Each

= 12( 10)

= 120

= 120  Rs

80 % of pencils = (80/100)10 = 8

Pencil sold for 5 + 0.5 = 5.5 Rs

= 8(5.5)

= 44 Rs

Total Selling Price = 120 + 44 = Rs 164

Profit = 164 - 150  =14 Rs

Profit % = (14/150) * 100 =  9.33 %
