Answer:

amit paint 52 sq meter

Step-by-step explanation:

amit = 20%

amit and ahmad = 45%

ahmad = 75 sq meter  ( 25%)

1% of wall is 75/25 = 13/5

amit = 20%

13/5  x  20  = 52 sq meter

THUS , AMIT PAINTED 52 SQ METER OF THE WALL.

 Amit painted 60 square meters of the wall.

Explanation:

Let x denotes the total area of the wall ( in square meters).

Area of the wall painted by Amit = 20% of x= 0.20x  [Divide percent by 100 to convert it into decimal] (1)

Area of the wall painted by  Ahmad = 75 square meters

Area of the wall left unpainted = 55% of x= 0.55x

According to the question , we have

Total area=Area of the wall painted by Amit +Area of the wall painted by  Ahmad+Area of the wall left unpainted

x=0.20x+75+0.55x\\\\ x= 0.75x+75\\\\ x-0.75x=75\\\\ 0.25x=75\\\\\ x=\dfrac{75}{0.25}=\dfrac{7500}{25}=300

Area of the wall painted by Amit =  0.20(300)   [from (1)]

= 60 square meters

Therefore , Amit painted 60 square meters of the wall.
