Question
11, 9, 15, 41 ,157, 789
The following series are based on a specific pattern. In these series, one number is wrong. Find the odd one.Solution
11 × 1 – 2 = 9 9 × 2 – 3 = 15 15 × 3 – 4 = 41 41 × 4 – 5 = 159 159 × 5 – 6 = 789
Simplify: 3/5 + 0.4 × 2.5
16/15 of 21/28 of 321.5 = ?
(26)2 = {(20% of 40% of 18200) ÷ ?} × 1664 ÷ 128Â
82.3 × 644.7 × 723.4 × 815.85 = 72?
Simplify the following expressions and choose the correct option.
√2116 + 152 ÷ 9 - 33
√(?) ² = √7396 - √6889
116*2/3% of 18600 + 666*2/3% of 1290 = 457*1/7% of 1750 + 555*5/9% of 3150 + ?
If a nine-digit number 389x6378y is divisible by 72, then the value of √(6x + 7y) will be∶
32 × 3 (54 – 15) + 186 ÷ 3 ÷ 2 – (21)² = ?
