A man buys lemons at 3 for Rs. 5 and an equal number at 2 for Rs. 4. He mixes them and sells at 5 for Rs. 9. Find his gain or lo

melamori03 [73]

3 lemons cost = Rs. 5

Each lemon cost = Rs. 5/3

2 lemons Cost = Rs. 4

Each lemon cost =

$= \frac{4}{2} = \frac{2}{1} = 2$

Total Cost price of Each lemon =

$\frac{5}{3} + \frac{2}{1}$

LCM = 3

$\frac{5}{3} + \frac{2 \times 3}{1 \times 3} = \frac{6}{3} = \frac{5 + 6}{3} = \frac{11}{3}$

Each lemon Cost =

$= \frac{11}{3} \div \frac{2}{1}$

$= \frac{11}{3} \times \frac{1}{2}$

$= \frac{11}{6}$

Selling price of 5 lemons = 9

Selling price of 1 lemon = 9/5

$loss\% = \frac{loss \times 100}{CP}$

$= \frac{ \frac{4}{6} - \frac{9}{5} \times 100 }{ \frac{11}{6} }$

$= \frac{\frac{55 - 54}{30} \times 100}{ \frac{11}{6} }$

$= \frac{\frac{1}{30} \times 100}{ \frac{11}{6} }$

$= \frac{100}{30} \times \frac{6}{11}$

$= \frac{20}{1} = 1 \frac{9}{11} \% \: loss$

An experienced cashier at a grocery store takes 2 seconds to scan each item and 40 seconds to process the customer's payment. 1)

grigory [225]

Answer:

The correct option is D) 43 items.

Step-by-step explanation:

As we know that total given time is ,

$Y = (60\times2) +6 =126\hspace{0.15cm} sec$ ,

Out of which cashier spends 40 seconds to process the customer's payment.

So the remaining time = (126 - 40) = 86 secs.

And the remaining time is used to scan the item and so that we can calculate here the no items scan is = (86 ÷ 2) = 43.

Therefore we can say that 43 items are being purchased.

A game of chance involves rolling a 16-sided die once. If a number from 1 to 3 comes up, you win 4 dollars. If the number 4 or 5

STALIN [3.7K]

Answer:

-$1.8

or loss of $1.8

Step-by-step explanation:

Given the following parameters, we have

The probability of winning $4 is 3/16

The probability of winning $7 is 2/16

The probability of losing $5 is 11/16

E(X) = (4 * 3/16) + (7 * 2/16) + (-5 * 11/16)

= 12/16 + 14/16 - 55/16

= -29/16

= -1.8

Hence, your expected net "winnings" would be -$1.8. That's an expected loss of $1.8.
