Directions (1-5) :

12 * 6 + 12 = 84

84 * 5 + 12 = 432

432 * 4 + 12 = 1740

1740 * 3 + 12 = 5232

5232 * 2 + 12 = 10476

23 + 22 * 2 = 31

31 + 32 * 2 = 49

49 + 42 * 2 = 81

81 + 52 * 2 = 131

131 + 62 * 2 = 203

32 * 5.5 = 176

176 * 5.5 = 968

968 * 5.5 = 5324

5324 * 5.5 = 29282

29282 * 5.5 = 161051

120 + 232 = 649

649 + 192 = 1010

1010 + 172 = 1299

1299 + 132 = 1468

36 * 37 = 1332

Directions (6-10) :

1/Amit = 1/60

1/Amit + 1/Rahul = 7/180

=> 1/60 + 1/Rahul = 7/180

=> 1/Rahul = 7/180 – 1/60

=> 1/Rahul = (7 – 3)/180

=> 1/Rahul = 4/180

=>1/Rahul = 1/45

1/Bhagat = 1/(45 – 15)

=>1/Bhagat = 1/30

3 days’ work = 1/60 + 1/60 + (1/60 + 1/45 + 1/30)

=>3 days’ work = (3 + 3 + 3 + 4 + 6)/180

=>3 days’ work = 19/180

=> 3 x 9 = 57 days’ work = 19/180 x 9 = 171/180

Remaining work = 1 – 171/180

= (180 – 171)/180

= 9/180

= 1/20

58 day’s work = 1/60

59 day’s work = 1/60

Remaining part of the work = 1 – 171/180 – 1/60 – 1/60

= (180 – 171 – 3 – 3)/180

= (180 – 177)/180

= 3/180

= 1/60

Let time taken by them to complete remaining part of the work = n

n x (1/60 + 1/45 + 1/30) = 1/60

=> n x (3 + 4 + 6)/180 = 1/60

=> n = 1/60 x 180/13

=> n = 3/13

Required time = 59 + 3/13 = 59 3/13

Place value of (A) = 59 (3/13)

1/Seema = ½ x 1/45

=>1/Seema = 1/90

Let time taken by them to complete remaining part of the work = n

5/60 + 5/30 + n x (1/60 + 1/30 + 1/90) = 1

=> 1/12 + 1/6 + n x (3 + 6 + 2)/180 = 1

=> 11n/180 = 1 – 1/12 – 1/6

=> 11n/180 = (12 – 1 – 2)/12

=> n = 9/12 x 180/11

=> n = 135/11

Place value of (B) = 135/11

Let, Reeta alone can complete the work in n days.

10/90 + 80/3n = 1

=> 1/9 + 80/3n = 1

=> 80/3n = 1 – 1/9

=> 80/3n = (9 – 1)/9

=> n = 80/3 x 9/8

=> n = 30

1/Reeta = 1/30

Let, Amit and Reeta together can complete the work in t days.

t x (1/60 + 1/30) = 1

=> t x (1 + 2)/60 = 1

=> t = 60/3

=> t = 20 days.

Place value of (C) = 20

1/Garima + 1/Rahul = 13/90 x 1/2

=>1/Garima + 1/45 = 13/180

=> 1/Garima = 13/180 – 1/45

=> 1/Garima = (13 – 4)/180

=> 1/Garima = 9/180

=>1/Garima = 1/20

Let, required number of days = n

5/20 + 5/30 + n/30 = 1

=> ¼ + 1/6 + n/30 = 1

=> n/30 = 1 – ¼ – 1/6

=> n/30 = (12 – 3 – 2)/12

=> n = 30 x 7/12

=> n = 35/2 days

Place value of (D) = 35/2

Let, required number of days = n

n x (1/30 + 1/90 + 1/60 + 1/30) = 1

=> n x (6 + 2 + 3 + 6)/180 = 1

=> n = 180/17 days

Place value of (E) = 180/17
