1) A grocer sold 5 kg of wheat flour at Rs 30 per kg and gained 20%. If he had sold

natita [175]

Answer:

given,

selling price (sp)=rs 5 ×30

=rs 150

now, gain %=20%

cost price (cp)=

$\frac{sp \times 100}{100 + gain\%}$

$= \frac{150 \times 100}{100 + 20}$

therefore cp= rs125

now,

again in 2nd case

sp= rs 27×5

therefore sp=rs 135

and cp= rs125

now, sp>cp so,

$gain\% = \frac{sp - cp}{cp} \times 100\%$

or, gain=

$= \frac{135 - 125}{125} \times 100\%$

therefore gain %= 8%.... is answer

hope it helps..

In the school election James ran against Ben for secretary James received 75% of the votes if 240 students voted how many votes

scoray [572]

Answer: James did not received 60 votes.

Step-by-step explanation:

Given: In a school election,

Percentage of votes received by James = 75%

Percentage of voted hadn't received by James = 100% - 75% = 25%

If 240 students voted , the number of votes hadn't received by James= 25% of 240

$=\dfrac{25}{100}\times 240\\\\=\dfrac14\times240\\\\=60$

Hence, James did not received 60 votes.

What 2 numbers should be used to find 231 - 198 using the 10 method for subtracting quickly in your head?

Airida [17]

Answer: "Count 2 and then count 31 more."

Step-by-step explanation:

We have the equation:

231 - 198

Now, the negative number is kinda ugly, so i will write it as:

200 - 2 = 198

Is a lot easier work with 200 and 2, than with 198.

Then the equation is now:

231 - (200 - 2)

And the left number we also have a "200", so it can be written as:

200 + 31 = 231

As this is a sum, we can ignore the parentheses.

200 + 31 - 200 + 2

31 + 2

Then the correct option is:

"Count 2 and then count 31 more."
