  Q.1) In a mixture of milk and water, their ratio is 5:6 respectively in the first container. And the same mixture has ratio 7:2 respectively in the second container. What is the ratio should the mixture be extracted from each container and poured in to the third container, so that the ratio of milk and water comes to 6:5 respectively in the third container?
  
  a) 99:253
  
  b) 253:99
  
  c) 243:88
  
  d) 88:243
  
  e) None of these
  
  b
  
  x litres of mixture be taken from the first container and poured into the third container.
  
  Let y litres of mixture be taken from the second container and poured into the third container.
  
  Quantity of milk in x litres=5/11 x
  
  Quantity of milk in y litres=7/9 y
  
  Quantity of milk in third container = 5/11 x+7/9 y
  
  Similarly, quantity of water in third container,
  
  =6/11 x+2/9 y
  
  (5x/11+7y/9)  :(6x/11+2y/9)=6 :5
  
  ((45x+77y)/99)/((54x+22y)/99)=6/5
  
  =>324x-225x=385y-132y    =>99x=253y   =>x/y=253/99
  
  =253 :99
  
  Q.2) The ratio of the price of two houses was 17:24. Two years later, when the price of the first had risen by 20% while the price of second house increases by Rs.500 and their prices become 16:25. Find the original prices of the two houses together?
  
  a) Rs.2603
  
  b) Rs.2503
  
  c) Rs.2403
  
  d) Rs.2303
  
  e) None of these
  
  a
  
  Let, new price of the first house=17x×120/100=102x/5
  
  Let, new price of the second house=24x+500
  
  According to the question,
  
  (102x/5)  :(24x+500)=16 :25
  
  ((102x/5))/((24x+500 ) )=16/25      =>102x×5=(24x+500)16    =>x=8000/126=4000/63
  
  Original price of first house=17×4000/63=1079.37~ Rs.1079
  
  Original price of second house=24×4000/63=1523.81 ~ Rs.1524

  a) 215
  
  b) 115
  
  c) 315
  
  d) 415
  
  e) None of these
  
  c
  
  Let the savings of A and B are 5x, 6x and the share cost of gift are 4y, 5y respectively.
  
  According to question,
  
  ForA,  5x-4y=3/4×5x     =>x=16y/5
  
  For B,  6x-5y=497         =>6×16y/5-5y=497    =>y=35
  
  Q.4) Nandita scores 60% marks in five subjects together, viz., Hindi, Science, Mathematics, English and Sanskrit, where in the maximum marks of each subject were 105.

  a) 66
  
  b) 68
  
  c) 55
  
  d) 65
  
  e) None of these
  
  d
  
  Total of maximum marks of all subjects=105×5=525
  
  75% of 525=525 ×60/100= 315
  
  Obtained marks of foru subjects (Hindi, Sanskrit, mathematics and English)
  
  =69+62+68+51=250
  
  So, the obtained marks in Science=315-250=65
  
  Ans=d) 65

How many coins did Parat receive from his father?
  
  a) 1210
  
  b) 1211
  
  c) 1212
  
  d) 1213
  
  e) None of these
  
  a
  
  According to question
  
  41x+40+34x+20+46x+30=4325      =>121x=4325-90     =>x=35
  
  number of coins recevied by parat
  
  =34x+20=34×35+20=1210
  
  Q.6) The sum of the ages of the 4 members of Sinha family is 172 years. 8 years ago the ages of the 4 members Nishu, Vicky, Mrs.Sinha and Sinha were in the ratio of 2:3:7:8. After how many years would Nishu be as old as the present age of his mother?
  
  a) 33 years
  
  b) 35 years
  
  c) 36 years
  
  d) 37 years
  
  e) None of these
  
  b
  
  Let their ages 8 years ago be 2x, 3x, 7x, and 8x.
  
  Their ages now 2x+8, 3x+8, 7x+8, 8x+8.
  
  According to the question,
  
  =2x+8+3x+8+7x+8+8x+8=172
  
  20x+32=172    =>x=140/20=7
  
  Present age of Nishu=2×7+8=22 years
  
  Present age of mother=7×7+8=57 years
  
  Hence, required years (57-22)=35 years
  
  Q.7) The work done by a man, a woman and a child is in the ratio of 2:3:4. There are 10 men, 20 women and 30 children in a factory.

  a) 2270
  
  b) 2440
  
  c) 3408
  
  d) 3230
  
  e) None of these
  
  c
  
  Total Wages of a men=1/10×1600=160
  
  Wages of a men=160/10  =16
  
  Similarly, women→24;     Child→32;
  
  Total wages of 15 men, 21 women and 30 children=15×16+21×24+30×32=240+504+960=1704
  
  Total wages of 2 weeks=1704×2=3408
