Solution

1.Let Ronit’s monthly salary be Rs. X
   30% of his monthly salary = Rs.30/100 = Rs.3x/10
   Rent : Transportation : Bills = 7 : 5 : 3
   Sum of the terms of ratio = 7 + 5 + 3 = 15
   According to the question,
                      5/15 × 3x/10 = 3560
                       Or, x = 3560 × 10 = Rs. 35600

2.Number of members in club Liverpool:
   Year 1992 = 120
   Year 1995 = 195
   Increased% = [(195 -120)/120] × 100 = 62.5%

3.Required difference = (169 + 205)   ̶   (121 + 147) = 106

4.Rqrd avg = (189 + 189) : (129 + 177)
                   = 378 : 306
                   = 21 : 17

5.Required ratio = (133+164+234)/3 = 177

6.Number of members in football clubs Man Utd, Arsenal and Liverpool in the year of 1994
     = 113 + 129 + 178 = 420
   Now, number of male members = 45% of 420
                                                       = 420 ×45/100 = 189

7.The pattern is : 18
                            18 + 1 × 19 = 18 + 19 = 37
                            37 + 2 × 19 = 37 + 38 = 75
                            75 + 3 × 19 = 75 + 57 = 132
                          132 + 4 × 19 = 132 + 76 = 208
                          208 + 5 × 19 = 208 + 95 = 303

8.The pattern is : 220
                            220 + 9 × 1 = 229
                            229  ̶  9 × 2 = 211
                            211 + 18 × 2 = 247
                            247  ̶  36 × 2 = 175
                            175 + 72 × 2 = 319

9.The pattern is : 3
                            3 × 1 + 1 = 4
                            4 × 2 + 1 = 9
                            9 × 3 + 1 = 28
                          28 × 4 + 1 = 113
                        113 × 5 + 1 = 566

10.The pattern is : 24
                              24 × 0.5 = 12
                              12 × 1.0 = 12
                              12 × 1.5 = 18
                              18 × 2.0 = 36
                              36 × 2.5 = 90
