Question
If 14,   32,    x,   50,   Â
-13,   86, then, find the value of (10x + 5x – 20)? In each of the following questions the number series is given. One term of the series is denoted by x. You have to calculate of value of x and by using the value of x, you have to solve the following questions.Solution
14 + 9 × 2 = 32 32 - 9 × 3 = 5 5 + 9 × 5 = 50 50 - 9 × 7 = -13 -13 + 9 × 11 = 86 Then, (10x + 5x – 20) = 10 × 5 + 5 × 5 – 20 = 50 + 25 – 20 = 55
The greatest number that will divide 398,436, and 542 leaving 7, 11, and 15 as remainders, respectively, is:
