16. (A) Numbers divisible by 7 between 100 and 200 = 14 Numbers divisible by 9 between 100 and 200 = 11 Numbers divisible by both 7 and 9 (i.e. divisible by 63) between 100 and 200 = 2 So the answer = 14 + 11 2 = 23

17. (B) Let the total work be 216 units One day work of A and B = 18 units One day work of B and C = 27 units One day work of A and C = 24 units One day work of 2A, 2B and 2C = 69 units One day work of A, B and C =69/2= 34.5 units Hence, work can be completed in =216/34.5 days =144/23 days 18. (B) Let the ages of Rani and Mani in 1996 be 2x and 3x respectively. 2+5

3+5 =

7

11

so, x= 15 2+15

3+15=

45

60=

3

4

19. (D) Ways of selecting 2 men = 4C2 = 6 Ways of selecting 3 women = 5C3 = 10 The total number of ways = 6 10 = 60 20. (C) Let their incomes be 5x, 8x and 9x respectively. 9x 8x = x = 12550 5x = 5 12550 = 62750

21. (A) C.P. of the mixture =(2455+5675)

80

= Rs. 69/kg

S.P. of the mixture to make a profit of 20% = 696

5

= Rs. 82.8/kg


22. (B) Let the present ages of P and Q be 5x and 6x So 5x + 6x = 55, 11x=55 x= 5 Age of Q is= 6x=6 5= 30 years

23. (A) Average age of A, B & C=7 Sum of ages of A, B & C=73=21 Average age of A & B=6 Sum of ages of A & B =62=12 Average age of B & C=8 Sum of ages of B & C =82=16 A + 2B + C= 12 +16 =28 A + B + C +B =28 21+B=28 B=28-21=7

24. (B)1 Dozen = 12 mangoes 16 dozen = 1216 = 192 mangoes Price of 192 mangoes = 1685

126 mangoes = 1685

192 126

= 1100 (approx.)

25. (B) Effect on revenue receipts= x + y+

100

= (30) + (-20) + 30 (20)

100

= 4 % increase 26. (B) Let C.P. of 1st T.V. =x So 120% of X= 840 X= 700 Let C.P. of 2nd T.V. = y So 96 % of y=960 Y = 1000 Total S.P. =840 +960= 1800 Total C.P. = 700 +1000= 1700 Profit= 100

Profit %= 100

1700 100 %= 517

15 %

27. (C) Let money of A, B, C & D be 5x, 2x, 4x, 3x respectively So 4x- 3x=1000 x=1000 Share of B= 2x= 2 1000 = 2000 28. (B) Let the no. be X X-35 = 80% of X X= 175


So X 4

5 = 175

4

5

= 140 29. (E) Total no. of three digits = 900 No. without 6= 8 99= 648 No. with 6 as digit= 900-648= 252 30. (D) Let the age of Meenu 5 years ago be x years So the age of Meenus mother 5 year ago = 3x Present age of Meenu= x +5 Present age of Meenus mother = 3x +5 After 5 years

So +5+5

3+5+5=

1

2

So X= 10 Present age of Meenu=15 years 31. (B) Total age of 5 member family at present= 20 5 =100 Total age of 6 member family at present = 17 6 =102 So the age of the child = 102- 100= 2 years 32. (E) For 2 years C.I. - S.I. = P .R2 / (100)2

90= .1212

100100

P= 6250

So A= P (1+

100)3

So A= 8780.80 33. (B) Price of one pair shoes= 99.99 Price of 15 pairs shoes= 99.99 15 = 1500 34. (D) a:b= 2:3 , b : c= 4:5 So a:b:c= 8: 12 : 15 So a2 :b2 : bc= 82 : 122 : 12 15 = 16: 36: 45 35. (B) Let the height of cone be h Radius of cone=r Volume = r2 h New Height = 3h, Radius= r/2 Volume= r2/4 3h

So volume decrease = 1

4 (r2h)

Decrease %= 25 36. (D) The Sum of 50 observations = 36 50 =1800


The Sum of 50 observations should be= 1800+25 = 1825 New avg. = 1825/ 50=36.50

37. (A) Percentage reduction= 25

125 100 %

=20 % 38. (B) 30% of A's salary = 20% of 3/5th of B's salary So A salary= 2/5 of Bs salary Bs salary= 2400 So As salary= 960

39. (D) C.I. - S.I. = 2(300+)

1003

So 620= 102 (300+10)

1002

P= 20,000

40. (A) Avg. Speed =

=2500+1200+500

5+3+2

=420 km/ hr
