Explanation

First, we need to calculate the number of voters who forget to vote.

7% of 5860 is approximately 410 voters.

Now, let's subtract those voters from the total: 5860 - 410 = 5450. Since the candidate needs to win at least 50% of the remaining votes, we'll divide 5450 by 2.

This gives us 2725 votes.

So, the candidate needs 2725 votes to win the election.

Explanation

 Number of population who read magazine

= (45 + 55 + 40) - (30 + 25 + 15) + 10

= 140 _ 70 + 10

= 80%

Number of population who do not read magazine

= 100 - 80 = 20% 

Explanation

22-karat gold, which contains 91.6% pure gold and 8.4% other metals like copper and silver,

It is commonly called "916 gold" or "22K gold" and is typically identified by a hallmark stamp indicating its purity. 

Explanation

To find the profit percentage:

Cost Price (CP) = Rs. 50

Selling Price (SP) = Rs. 75

Profit = SP - CP = 75 - 50 = Rs. 25

Profit Percentage = (Profit / CP) × 100

= (25 / 50) × 100

= 50%

Explanation

1/240 * n * 4 = 6 becomes:

1/240 * 360 * 4 = 6

we simplify to get:

6 = 6 confirming that our calculation of the number of people required is good.

the answer is that it would require 360 men to fill 6 holes in 4 months.

Explanation

Let x be volume of the solution

 8/100 × x = 15.

8/100 = 15/x. Cross multiplication.

8x = 15×100.

x = 15 × 100/8.

= 187.5 ml. 

Explanation

10% of 5400 = 540

5400 - 540 = 4860

Explanation

50 to 60:

Increase = 60 - 50 = 10

Percent increase = (10 / 50) × 100 = 20%

Explanation

Let's denote the number as x. According to the problem:

45 = 0.72x

To find x, divide both sides by 0.72:

x = 45 / 0.72

x = 62.5
