Question
The series given below contains a sequence of numbers.
Accordingly identify the incorrect number. 85, 84, 81, 88, 77, 92, 72Solution
The series alternates between decreasing and increasing numbers, with the difference between them following a pattern where each step varies by a multiple of 4. Correct sequence following that pattern: Â 85 - 4 = 81 81 + 8 = 89 89 - 12 = 77 77 + 16 = 93 93 - 20 =Â 73 The original sequence given was: 85, 84, 81, 88, 77, 92, 72 Analyzing the given sequence: 85 - 1Â = 84 84 - 3Â = 81 81 + 7Â = 88 88 - 11 = 77 77 + 15 = 92 92 - 20 = 72 The incorrect numbers, when compared to the pattern, are: 84 (should be 81), 88 (should be 89), 92 (should be 93), 72 (should be 73).
36% of 640 – 12.5% of 352 + 25% of 640 = ? – 48% of 432
?% of 320 - 69 = 123
(13)2 + 6 × (19)2 – 312 × 4 = ?
(22.5 × 24) ÷ 40 + 51.50 = ? ÷ 5.25
I. x² + 3x – 154 = 0
II. y² + 5y – 126 = 0
32 of (16/8) of (30/24) of (120/x) = 30
Find the value of the expression:
18 + 12 – 4 × [22 + 6 – 2 × (38 – 23)]- What will come in place of (?), in the given expression.
125% of 96 + 33% of 300 = ? 150% of 850 ÷ 25 – 25 = ?% of (39312 ÷ 1512)
121/? = ?/144
