Question

1000 of eggs buy a seller man and there is damge 90eggs .and rest egg he every 12eggs selling price of 9.60 rupees..and he lose 12%

Answer 1

Answer:

Rs. 9100/11

Step-by-step explanation:

man bought 1000 eggs & damaged 90

so remaining eggs, 1000 - 90 = 910

now, selling price of 12 eggs = Rs 9.60

S.P of 1 egg = 9.60 ÷ 12 = 80 paisa

S.P of remaining 910 eggs = 910 × 80 paisa = Rs 728.00

{we can solve with two different methods}Let, the cost price of 1000 eggs = x

loss of 12% = C.P. × loss% => 12x/100 = 3x/25 (reducing the fraction to lowest by extracting and cancelling out 4)

we know, C.P - loss = S.P

so, x - 3x/25= 728

⇒(25x-3x)/25 = 728

⇒22x/25 = 728 ⇒22x = 728 × 25

⇒x = (728 × 25)/22 ⇒x = 18200/22

⇒x = 9100/11 Rs

Alternative:

loss of 12% means

when, Cost Price = 100, loss = 12

So, Selling Price = C.P - loss ⇒100-12 = 88

Now,

for Selling Price 88, Cost Price = 100

for Selling Price 1, C.P = 100/88

for Selling Price 728, Cost Price will be = 728 × 100/88 = 9100/11
