The correct option is A 552
From the figure
4y = x-------->(1)
From second part of the figure,
2x + y = 1242
⟹ 2(4y) + y = 1242
⟹ 8y + y = 1242
⟹ 9y = 1242
⟹ y = 12429
⟹ y = 138
Substitute the value of y in equation (1), we get:
4(138) = x
⟹ x = 552
Here, x indicates the value of house. So, the value of a house is 552.
