In each of the following questions one number is wrong. Find the wrong number.Solution
The series is ÷ 2 + 4 (repeated) 2592 ÷ 2 + 4 = 1300, 1300 ÷ 2 + 4 = 654, 654 ÷ 2 + 4 = 331, 331 ÷ 2 + 4 = 169.50, 169.5 ÷ 2 + 4 = 88.75,..... Therefore it should be 654 in place of 656.
15.99% of 549.99 ÷ 11.17 = ? ÷ 20.15
74.91% of 639.95 – 599.98% of 45 + 119.987 = ?
(4.88 × 5.76)2 - ?2 = 39.89 × 19.86

(1800.23 ÷ 29.98) + (816.32 ÷ 23.9) + 1634.11 = ?
1449.98 ÷ 50.48 × 10.12 = ? × 2.16
36.05 × 5.02 + 12.052 = ? + 9.09 × 4.04Â
(31.9)3 + (34.021)² - (16.11)3 - (42.98)² = ?
