The correct option is B
Area of wall A = 1554 sq.m.
Gap between two paintings for wall A = 26 m
Area of wall B = 1600 sq.m.
Gap between two paintings for wall B = 25 m
To find the wall which can accomodate more number of paintings, divide 1534
On doing the division by standard algorithm method,
So, for wall A, number of paintings will be =59
And, for wall B, number of paintings will be =64
You know, 64>59
Hence, out of the two walls, wall B
will have more number of paintings.
