Answer:

57,900 paisa

Explanation:

20m x 10m x 2 = 400 square meters of floor and ceiling

20m x 6.5m x 2 = 260 square meters of 2 walls

10m x 6.5m x 2 = 130 square meters of other 2 walls

Surface area of room is 790 square meters

2.4m x 1.25m x 4 = 12 square meters of doors

1.25m x .6m x 8 = 6 square meters of windows

790 - 18 = 772 square meters

75 paisa x 772 square meters = 57,900 paisa
