Question
Identify the number that does NOT belong to the
following series. 3, 7, 12, 21, 57, 109, 276, 499Solution
Seies = 3, 7, 12, 21, 57, 109, 276, 499 Logic : the series is based on double difference Pattern: First difference is cube of numbers and it is in alternate places Second difference is of square of the numbers and it is in alternate places as well. Series of difference = 4, 5, 9, 36, 52, 167 , 223. Series of double difference = 1, 4, 27, 16, 115 , 56. Instead of 115, 125 will be placed. Â
(1748 ÷ 8) + 76.8 × 35 =(? × 4) + (42 × 35.5)
(560 ÷ 32) × (720 ÷ 48) = ?
What will come in the place of question mark (?) in the given expression?
642 - 362 = ? X √1225
- Calculate the value of x if x% of 400 plus {800 ÷ x of 8} × 4 is equal to 88
Simplify the following expression:
(3/5 of 250 + 40% of 150) ÷ (0.75 of 80)

(92.03 + 117.98) ÷ 14.211 = 89.9 – 30.23% of ?
- What will come in place of (?), in the given expression.
(81 ÷ 9) + (121 ÷ 11) + (64 ÷ 8) = ?
