Explanation

A can do the work in 4 hours, so A's work rate is 1/4 of the work per hour.

B and C can do the work in 3 hours, so their combined work rate is 1/3 of the work per hour.

A and C can do the work in 2 hours, so their combined work rate is 1/2 of the work per hour.

Now, let's find B's work rate:

B and C's combined work rate is 1/3 of the work per hour, and A and C's combined work rate is 1/2 of the work per hour. Since A's work rate is 1/4 of the work per hour, C's work rate can be found by subtracting A's work rate from the combined work rate of A and C: (1/2 - 1/4) = 1/4 of the work per hour. So, C's work rate is also 1/4 of the work per hour.

Now, we can find B's work rate by subtracting C's work rate from the combined work rate of B and C: (1/3 - 1/4) = 1/12 of the work per hour.

Since B's work rate is 1/12 of the work per hour, B alone will take 12 hours to complete the work.

Explanation

Profit = Selling Price - Cost Price

= 540 - 470

= 70

Profit Percentage = (Profit ÷ Cost Price) × 100

= (70 ÷ 470) × 100

= 15 (14.89%)

Explanation

x = 7 — 4√3, we are required to find x + 1/x.

1/x = 1/(7 — 4√3)

Rationalising 1/x,

1/x = {1/(7 —4√3)} × {(7 + 4√3)/7 + 4√3)} = {(7 + 4√3)}/{7² — 4²(√3)²} = (7 + 4√3)/(49 — 48) = 7 + 4√3.

Therefore

x + 1/x = 7 — 4√3 + 7 + 4√3 = 14.

Explanation

When 52416 is divided by 312, the quotient is 168. To find the quotient when 52.416 is divided by 0.0168, we can set up a proportion:

52416 ÷ 312 = 168

52.416 ÷ 0.0168 = x

We can then cross-multiply and solve for x:

x = (52.416 × 312) ÷ 0.0168

x = 3120

So, the quotient is 3120.

Explanation

Let's calculate the amount that is 10% of the annual production sales:

Annual production sales = 3481600

10% of annual production sales = (10/100) × 3481600

= 348160

Explanation

Zakat is typically 2.5% of the total wealth.

To find the total amount, divide the Zakat paid by 0.025 (8500 ÷ 0.025 = 340,000).

Explanation

Current sum of ages = 100 years

5 years ago, their ages were in the ratio of 2:1. Let's call the father's age 5 years ago "2x" and the son's age 5 years ago "x".

We know that 5 years ago, their sum of ages was:

2x + x = 3x

Since the current sum of ages is 100, we can set up an equation:

(2x + 5) + (x + 5) = 100

Combine like terms:

3x + 10 = 100

Subtract 10 from both sides:

3x = 90

Divide by 3:

x = 30

So 5 years ago, the father's age was 2x = 60 and the son's age was x = 30.

Now, let's find their ages after 10 years:

Father's age = 60 + 5 + 10 = 75

Son's age = 30 + 5 + 10 = 45

The ratio of their ages after 10 years is:

75:45 = 5:3
