Question

3/8 part of a wall is coloured yellow and 5/12 part blue. The remaining part is coloured green. How many metre square of the wall is coloured green. If the area of the wall is 240 metre square?

Answer 1

Answer:

3/8×240=90sq.m yellow area

5/12×240=100sq.m blue area

green area =240-(yellow area + blue area)

=240-(90 + 100)

=240-190

=50sq.m

Answer 2

The area of wall colored green is 50 square meters.

Explanation:

Given : Part of wall colored yellow =$\dfrac{3}{8}$

Part of wall colored blue = $\dfrac{5}{12}$

Total area of wall = 240 metre square.

Area of wall colored yellow =(Part of wall colored yellow) x (Total area of wall )

$=\dfrac{3}{8}\times240=90\text{ square meters}$

Area of wall colored blue =(Part of wall colored blue) x (Total area of wall )

$=\dfrac{5}{12}\times240=100\text{ square meters}$

Area of wall colored green = (Total area of wall )-(Area of wall colored yellow)-( Area of wall colored blue)

=240-90-100=50 square meters

Hence, the area of wall colored green is 50 square meters.
