Question
If   20       x      46  Â
   147       604        3045 Then, x% of 25 = ? In each of the following questions a number series is given. One term of the series is denoted by  X . You have to calculate the value of  X  and by using the value of  X , you have to replace the question mark (?) in the following questions :Solution
20 × 1 + 1² = 21 21 × 2 + 2² = 46 46 × 3 + 3² = 147 147 × 4 + 4² = 604 604 × 5 + 5² = 3045 Hence, x = 21 Hence, 25×21/100 = 21/4 = 5.25
