Explanation

Let daughter age = x

Father age = 5 times daughter age = 5x

Sum of ages = 50

x + 5x = 50

6x = 50

x = 50 / 6 = 8.33

So daughter = 8.33 years

Father = 5 x 8.33 = 41.67 years

Explanation

Let's place them one by one:

1. Lahore is not to the East of Karachi

   So Lahore is West / North-West / South-West of Karachi.

2. Islamabad is to the North of Lahore 

   So Islamabad is directly North of Lahore.

3. Peshawar is to the West of Islamabad 

   So Peshawar is West of Islamabad.

Now combine:  

Karachi → Lahore is somewhere West.  

Lahore → Islamabad is North.  

Islamabad → Peshawar is West.  

So from Karachi, go West to Lahore area, then North to Islamabad, then West again to Peshawar.

That puts Peshawar to the North-West of Karachi.

Explanation

Formula: Amount = Principal _ (1 + r/100)^n

Given:

Amount = 1.44 _ Principal

n = 2 years

Put values:

1.44 _ P = P _ (1 + r/100)^2

Cancel P from both sides:

(1 + r/100)^2 = 1.44

Take square root both sides:

1 + r/100 = 1.2

r/100 = 1.2 - 1 = 0.2

r = 0.2 * 100 = 20
