Area of the poster = 2.5 × 2.5 sq. m
= 6.25sq.m Area of the wall

Calculation:

To find the area of the remaining part of the wall that needs to be painted, we first need to calculate the area of the square wall poster and then subtract it from the total area of the wall.

Area of the square wall poster:
Given side of the square = 2.5 m
Area of a square = side x side
Area of the square wall poster = 2.5 x 2.5 = 6.25 sq. m

Total area of the wall:
Length of the wall = 10.5 m
Width of the wall = 8.5 m
Total area of the wall = Length x Width
Total area of the wall = 10.5 x 8.5 = 89.25 sq. m

Remaining area to be painted:
Remaining area = Total area of the wall - Area of the square wall poster
Remaining area = 89.25 - 6.25 = 83 sq. m

Cost of painting the remaining area:
Cost per sq. m = Rs. 12
Total cost = Cost per sq. m x Remaining area
Total cost = 12 x 83 = Rs. 996

Therefore, the cost of painting the remaining part of the wall with pink color is Rs. 996. Hence, the correct answer is option B.
