Answer & Explanation

  1. 3

Ratio: 90/108 = 5/6

 

  1. 4

Sum = 108 + 30 = 138

 

  1. 1

Diff = 162 – 60 = 102

 

  1. 2

Ratio: 192/168 = 8/7

 

  1. 4

Req% = 162/90 * 100 = 180%

 

  1. 2

n(S) = 15C3 = (15 * 14 * 13)/6 = 455

2 red balls can be selected in 4C2 = 6 ways

 

And remaining one ball can be selected in 11C1 = 11 ways

P(E) = (6*11)/455 = 66/455

 

  1. 3

n(S) = 15C3 = 455

Three balls have to be selected from 4 red and 6 white balls

 

No. of ways = 10C3 = 120

P(E) = 120/455 = 24/91

 

  1. 4

n(S) = 15C3 =455

 

If all three balls are of same colour, then no. of ways = 4C3 + 5C3 + 6C3 = 4 + 10 + 20 = 34

P(E) = 34/455

 

For being different colours P(E) = 1 – 34/455 = 421/455

 

  1. 1

n(S) = 15C2 = 105

n(E) = 4C2 + 5C2C + 6C2 = 6 + 10 + 15 = 31

P(E) = 31/105

 

  1. 4

n(S) = 15C3 = 455

n(E) = 4C1 + 5C1 + 6C1 = 4 * 5 * 6 = 120

P(E) = 120/455 = 24/91
