Question

What is the cost of painting two adjacent walls of a hall having no door or window at Rs.450 pe `m^(2)`?
, I. Length and breadth are in the ratio of `3:2` respectively.
II Perimeter of the hall is 50 m and highht is one-fourth of the perimeter.
A. if the data in statement I alone are sufficient to answer the questin, while the data in statement II alone are not sufficient to answer the question.
B. if the data in statement Ii alone are sufficient to answer the questin, while the data in statemetn I alone are not suffcient to answer the question.
C. id the data in both statements I and II alone are surfficient to answer the question.
D. if the data in both statements I and II together are not sufficient to answer the question.

Answer 1

`{:(22.5 " "15),("Length: Breadth"=3:2),(" "darr),(" "3x:2x):}`
Height `=50xx1/4=12.5`
Perimeter `=2(3x+2x)=50impliesx=5`
So, area of two any adjacant walls
`=b xxh+1xxh=h(1+b)`
Total cost of painting on wall `=12.5xx25xx450=Rs.140625`
