Question
Select the number from among the given options that can
replace the question mark (?) in the following series. 2, 13, 29, 55, 96, 157, 243, ?Solution
2, 13, 29, 55, 96, 157, 243, ? First difference between 2 and 13 is 11, 13 and 29 is 16... and So on 157 and 243 is 86. Now, the difference between the differences is 5, 10, 15, 20, 25, and 30 respectively. So, the final answer is 359.
(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)
Train M, ‘x’ metres long crosses (x – 30) metres long platform in 22 seconds while train N having the length (x + 30) metres crosses the same plat...
(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) = ?
