2. Cost Price of 1 window  = 64,480

[MARK THE ANSWER AS BRAINLIEST]

Step-by-step explanation:

Let the distance travelled on foot be x km.

Foot Speed = 4 km/h

Then, distance travelled on bicycle = (61 -x) km

Bicycle Speed = 6 km/h

Total time = 9 hrs

$\frac{x}{4} + \frac{61-x}{9} = 9$

$\frac{9x + 4 (61-x)}{36} = 9$

9x + 244 - 4x = 324

5x = 324 - 244

5x = 80

x = 80/5

x = 16

Distance Travelled by Foot = 16km

-------------------------------------------------------------------------

Let the cost price of 25 windows be x

Off = 25%

Reduced Price = x - 25% of x

= x - x/4

= 3x/4

Additional Discount = 7000

Final Selling Price = 3x/4 - 7000

According to the question :

S.P = 1,20,2000 = Final Price

1202000 =  3x/4 - 7000

1202000 + 7000 = 3x/4

3x = (1209000) * 4

x = 1,61,2000

Cost Price of 25 windows = 1,61,2000

Cost Price of 1 window = 1,61,2000 / 25 = 64,480
