Question
If 16 15 26 69 260 x, Find 75% of x+
x 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
16 × 1 - 1², 15 × 2 - 2², 26 × 3 - 3², 69 × 4 - 4², 260 × 5 - 5², 1,275 Hence, x= 1,275 Hence, 75% of x+ x=956.25 + 1,275 = 2,231.25
