A pack of fruits has 100 units and its total cost is $117.5. If 17% of fruits in a pack are rotten, at least what is the unit selling price to earn a total profit of$90?

A. $2.2 B.$2.3
C. $2.4 D.$2.5
E. $2.6 17% percent fruits are rotten. Hence total number of good fruits = 83 We need to earn a profit of$90. Hence total selling price should be $117.5 +$90 = $207.5 Total fruits to be sold = 83 Hence selling price of each fruit =$207.5/83 = $2.5 Hence Answer = D Kudos 2 kudos, 0 bookmark ##### General Discussion Jul 16 at 08:05am Let SP of single fruit be x 83x-117.5=90 x=2.5 Posted from my mobile device Kudos 3 kudos, 0 bookmark Jul 16 at 08:09am IMO Answer is D: cost price of 100 units = 117.5$
17 are rotten so, 83 are good to sell
given profit is 90$So, SP-CP = 90 selling price = 83*x$
83x-117.5 = 207.5 ==> x =2.5$so answer is D Kudos 1 kudos, 0 bookmark Jul 16 at 08:11am Let the minimum selling price per piece be x, Then 83*x - 117.5 = 90 x = 2.5 Kudos 1 kudos, 0 bookmark Jul 16 at 08:14am A pack of fruits has 100 units and its total cost is$117.5. If 17% of fruits in a pack are rotten, at least what is the unit selling price to earn a total profit of $90? A.$2.2
B. $2.3 C.$2.4
D. $2.5 E.$2.6

Cost price of 100 units =$117.5 17% (17 units) are rotten Saleable units = 100 - 17 = 83 Sales for 83 units =$117.5 + $90 =$207.5
Sales price / unit = $207.5/83 =$2.5

IMO D

I went with D:

The total unit cost was $117.5 You need a profit of$90

So revenues need to be at least $207.5 (cost + profit) = Rev. or$117.5 + $90 =$207.5

Since 17% is rotten, you have to earn the revenues through the remaining inventory.
So 207.5/83 = 2.5 per unit

SP-CP = 90

CP of fruits = 117.5
SP = 90 + 117.5
SP = 207.5
Since 17% was rotten

SP per unit = 207.5/83 = 25$Answer should be D Kudos 1 kudos, 0 bookmark Jul 16 at 08:23am 100 fruits were bought at$1.175 per fruit ------------------- (Cost Price)

(100-17) fruits are to be sold at $x per fruit, where is x is the average selling price per unit ----------------- (Selling Price) We require that, (100-17)x = 100(1.175) + 90 83x = 207.5 x=2.5 Answer is (D) Kudos 1 kudos, 0 bookmark Jul 16 at 08:25am 100 units for 117.5$

17% of 100 fruits are rotten. So 83 fruits are not rotten.

For total profit of 90$, sale price should be 117.5+90=207.5 SP of per unit=$$\frac{207.5}{83}$$=$2.5

Hence option D

IMO D

A pack of fruits has 100 units and its total cost is $117.5. If 17% of fruits in a pack are rotten, at least what is the unit selling price to earn a total profit of$90?

A. $2.2 B.$2.3
C. $2.4 D.$2.5
E. $2.6 SOL: the total number of fruits=100, rotten=17 so left=83. now the CP of 100 fruits=117.5 and we need 90 profit. so we must sell 83 fruits for 207.5 that means each fruit has to be at least=207.5/83=2.5 D 2.5 atleast. Kudos 1 kudos, 0 bookmark Jul 16 at 08:27am The total fruits we have is 83 and profit is$90, so the total selling cost would be 117.5+90=207.5.

So unit selling price = 207.5/83=2.5

D

The packet has total 100 units of fruits and 17% or 17 units are rotten. That means that only 83 fruits have any worth.

Now, the cost of the packet is $117.5, however, we need$90 profit margin.

So, the packet should be selling for $117.5+$90 = $207.5 The packet has 83 units, so each unit should sell for 207.5/83 =$2.5/unit

IMO- D

Total Units = 100 units
Total cost = $117.5 Fruits rotten/park= 17% = 0.17 X 100= 17 Units Fruits Ok = 100-17= 83 units Total profit =$90

Total SP for 83 Units= $117.5 +$90 = $207.5 Least SP/Unit=$207.5/83 = $2.5 For any SP/unit greater than$2.5 profit will be greater than $90 Ans- D Kudos 1 kudos, 0 bookmark Jul 16 at 08:28am Cost - 117.5$ and Profit required - 90$. Total sales value - 207.5 and units available - 83. So per unit cost - 207.5/83 (sub answer options in 83*X=207.5) 2.4$ per fruit gives 199.2$. So unit price must be higher. 2.5$ gives 207.5 IMO D

Selling Price = Total cost + Profit
Total cost=117.5
Profit=90(Minimum)

SP=117.5+90=207.5

Now, as 17% units are rotten, we need to get profit from 83% which is 83 units.

So SP of each unit = 207.5/83=2.5
Hence D

A pack of fruits has 100 units and its total cost is $117.5. If 17% of fruits in a pack are rotten, at least what is the unit selling price to earn a total profit of$90?

Profits = Selling Price* #of units - Costs

So, if rotten units are 17%, we will have only 83 units, so

90 = 83*SP - 117.5

207.5 = 83*SP

SP = 2.5

Let the selling price per unit be $$x$$.

Profit = Total Selling Price (excluding roten units) - Total Cost of the units
$$90 = 83x-117.5$$

Which gives,
$$x=2.5$$

D has to be the right answer.
90 profit means 117.5 + 90 = 207.5

And 2.5x83(after reducing 17%) is 207.5

Simple and straight :
C.P : 117.5
S.P : 117.5 +90 = 207.5
Unit price: 207.5/100 = 2.075
now 17% of fruits are bad, so left fruits: 83 ,
Now to earn 90\$ profit, S.P cannot be changed but unit price will increase So
207.5 / 83 = 2.50
