Explanation

Let's denote Hassan's age as H and Nida's age as N.

Given:

1. H + 3N = 30

2. N = H/6

Substitute N = H/6 into the first equation:

H + 3(H/6) = 30

H + H/2 = 30

Multiply both sides by 2 to eliminate the fraction:

2H + H = 60

3H = 60

H = 20

Explanation

Length of the frame = 12 cm
Width of the frame = 8 cm

Perimeter of a rectangle = 2 × (length + width)

So, the perimeter $P$ is:
$P = 2 times (12 text{ cm} + 8 text{ cm})$
$P=2\times 20\text{ cm}$
$P = 40 text{ cm}$

Now, convert the perimeter from centimeters to meters (since the cost of ribbon is given per meter):
$\text{Perimeter in meters}<font\; color="\#0000ff">=</font>\frac{}{}$40 cm100text{Perimeter in meters} = frac{40 text{ cm}}{100}
$text{Perimeter in meters} = 0.4 text{ m}$

Next, calculate the total cost of the ribbon:
Cost of 1 meter of ribbon = Rs 5

Total cost of ribbon = Cost per meter × Length in meters
$text{Total cost} = 5 times 0.4$
$\text{Total cost}=Rs2$

Therefore, the total cost of the ribbon Nadia needs is Rs 20.

Explanation

Indirect to direct narration: "She was having" changes back to "I am having" in direct speech.

Since the reporting verb "said" is in the past and there’s no change in time reference, present continuous remains valid in the direct form.

Explanation

The sentence is in simple past tense, so the passive form uses "was + past participle."

"Gave" (past tense of give) changes to "was given" in passive voice.

Explanation

They are not classified into types.

Explanation

Let Haider's son's present age be x.

Haider's present age = 3x

After 10 years:

Son's age = x + 10

Haider's age = 3x + 10

The sum of their ages after 10 years will be 76:

x + 10 + 3x + 10 = 76

4x + 20 = 76

4x = 56

x = 14

Haider's present age = 3x = 3 × 14 = 42
