NICL Administrative Officer (AO) Finance Exam 2013 Question paper

Dry grapes contain 10% water.
Weight of dry grapes = 250kg
Therefore, weight of water part = 10% of 250 =kg
Weight of pulp part = 225 kg
Now, for fresh grapes to contain 80% water, 20% is pulp part.
20% of x = 225
x = 1225 kg
Therefore, the weight of grapes is = 1225kg
Option D is correct answer.
 

Side of triangle = 12 of  (1/8)th units = 12*(1/8) = 1.5 inches.
Now, x of (1/12)th units = 1.5 inches
Hence, x = 18.
Therefore, the correct answer is option A.
 

Let the common multiple be x.
Now, the materials cost is 234
Hence, (3/8)x = 234 i.e x = 624
Now, cost of labour = (4/8)x = (1/2) * 624 =312
Therefore, the correct option is option B.
 

Here, the HCF of 3.78 and 5.25 is 0.21.
Therefore, .21 will constitute as side of each square.
Number of square = (3.78 * 5.25)/(0.21*021) = 450
Hence, the correct option is option C.

Let the number of students be n and cost of food per student be x.
Now, 500/n = x
Also, lateron cost increases by 5when 5 students don't come.
500/(n-5) = x+5
500/(n-5) = 500/n +5
Solving we get
n = 25
Hence, number of students attending picnic was 20.
