In each of these questions, two equations (I) and (II) are given. You have to solve both the equations and give answer.
I. 2m2 + 11m + 12 = 0
II. 2n2 + 19n + 45 = 0
I. 21m2 − 23m + 6 = 0
II. 2n2 − 11n + 15 = 0
I. 25m2 + 25m + 6 = 0
II. 5n2 + 20n + 20 = 0
I. 20m2 − 17m + 3 = 0
II. 20n2 − 9n + 1 = 0
I. m2 + 14m − 72 = 0
II. 3n2 + 14n + 15 = 0
What will come in place of the question mark (?) in the following questions?(You are not expected to calculate exact values)
(19.97% of 781) + ? + (30% of 87) = 252
17.992 − 14.052 + (2343.75 + 81.65) ÷ ? = 229
8399.999 ÷ 375.002 × 14.996 = ?
2418.065 + 88 ÷ 21.6 × 6 = ?
9.7% of 240 × 14.89% of 480=?
