Correct Answer:
Explanation:
As per given all statements , we can see that
I. The area of the hall = 24 m2
II. The ratio of breadth, length and the height of the hall = 4 : 6 : 5
From II, Let L = 4x , B = 6x and H = 5x
Then, area of the hall = L × B = 4x × 6x
= 24x2 m2
? Area of the hall = 24 m2
? 24x2 = 24 ? x = 1 m
L = 4 x 1 = 4 m, B = 6 x 1 = 6 m and H = 5 x 1 = 5 m.
III. Area of one wall = 30 m2
Thus, area of two adjacent walls = [( L x H ) + ( B x H )] m2 can be found out and so the cost of painting two adjacent walls may not be found out.
Cost of painting is not given, hence data inadequate.

Correct Answer: Only I
Explanation:
From above given all statements , we have
I. Average salary of 7 clerical cadre employees = $ 8500.
Sum of salary of 7 clerical cadre employees = $ 8500 x 7 = $ 60000
II. Average salary of 5 officer cadre employees = $ 10000.
Sum of salary of 5 officer cadre employees = $ 10000 x 5 = $ 50000
III. Average salary of the 3 sub-staff employees = $ 2500.
Sum of salary of 3 sub-staff employees = $ 2500 x 3 = $ 7500
Average salary of 15 employees = Sum of salary of 7 clerical cadre employees + Sum of salary of 5 officer cadre employees + Sum of salary of 3 sub-staff employees = 60000 + 50000 + 7500 = $ 117500/15 = $ 7834
