2) A company bought twice as many as small envelopes than large envelopes. It is used up to 6/11 of small envelopes and 1/3 of large envelopes. What fraction was left unused?
3) A company has a employees of 30 csr on 1st shift and another 30 on second shift. On Monday 30 of them were taking calls. on Tuesday also 30 were taking calls and on Wednesday 40 of them take calls. On average what fraction of these csr’s were taking calls during these 3-days?

5) Creating a certain alloy requires 15% copper, 25% lead and 60% silver. If 5kgs of lead is present in that alloy. For what % of silver is added in the mixture?

6) There are 30 employees who are working in 4 modules. Instruction lead group pays $2500 per module and for 10 employees with room rental services and online team pays $200 per module for each employee and has the savings of $8000. What are the room rental services?

8) A computer hard disk has a storage capacity of 2GB. The hard disk is partitioned into 3 sections.
Section A has 900mb. Section B has 2/3 of amount of section A, minus 1/6 of amount of section C. section C has 3 times the amount of section B, minus the amount of section A, what % of hd space has been allocated to section A & C ? (note: 1GB=1000MB

• Ans 2)
  Let small envelopes bought=2x
  Large envelopes bought=x
  Total No. of envelopes bought=x+2x=3x
  Small envelope unused=(5/11)*2x=10x/11
  Large envelope unused=(2/3)*x=2x/3
  Total envelope unused=(24x/13)+(x/6)=52x/33
  Fraction of the total envelope unused=(52x/33)/3x=52/99

  Given 60% of 5 employees including 2 who are capable of doing task.
  
  60% of 5 employeees
  = 60/100 * 5
  = 3 employees
  
  ===> 2 employees who are capable of doing the task and one employee who is not capable.
  
  percentage of employees assigned who are not capable
  = 1/3 * 100
  = 33.33%

  Let there is x Kgs of alloy.
  Cooper present in mixture= 15/100 of x
  Lead present in mixture = 25/100 of x= 5 Kgs(Given)
  => By solving above expression : x= 20Kgs
  Silver present in mixture = 60/100 of x= (60/100) * 20 = 12 Kgs

  a=900mb
  b=2/3*A-1/6*c
  c=3(B-A)
  
  solving this B=700mb &c=400mb
  so A+c=1300mb
  so %of HD space=1300/2000*100=65%

• 5.) ratio of contents in the alloy is given to be :
  copper : lead : silver
  15/100 : 25/100 : 60/100 (make lead as 1 i.e divide by 25 each content)
  3/5 : 1 : 12/5 (no as per question make lead to be by multiplying by 5)
  3 : 5 : 12
  hence, we can this way get the ans to be 12kgs of silver .

  A+B+C = 2000
  A = 900
  B = 2/3A - 1/6B
  C = 3B - A
  
  
  B=1100 - C
  1100 - C = 600 - 1/6C
  C = 600
  
  B = 2/3A - 1/6C = 600 - 100 = 500
  
  A+C = 1500, 75% of 2000

• 6) instruction lead group can accommodate 10 employee for each class. so 30 employees need 3 class for each module. we have 4 modules, 4*3=12 classes are needed to complete the training. $2500 is charged for each class. The total expense for instruction lead group is 2500*4*3=30000. let the room rental service be x. The equation is 2500*4*3 + x = 200*30*4 + 8000. it becomes 30000 + x = 24000 + 8000. the answer x is 2000.

  As only 10 employees has room rental services and so they are paid $200 per module so each of them gets $800 ..then the savings become $(10000-800 )= $9200 .. but due to rental services the saving is shown to be $8000 ... so the amount of rental service is $(9200-8000)=$1200.
