Question
If in all the numbers the digits are arranged in an
descending order, then which number newly formed is the lowest among all? Study the following questions below which are based on the six three digits numbers: 893Â Â 479Â Â 216Â Â 526 Â 372Â Â 685Solution
893Â Â 479Â Â 216Â Â 526 Â 372Â Â 685
983Â Â 974Â Â 621 Â Â Â 652Â Â 732 Â 865
 The lowest number after arranging is 216.Â
Find the missing number in the given number series.
 58, 86, 142, ?, 478, 926
7, 6, 10, 27, 104, ?Â
Find the missing number (?) in the given number series.
2, 6, 18, 54, ?, 486
A series given below follows a certain pattern,
1800, 469, (?), 855, 980, 953
If (?) = B – 2, then find the nearest cube root of B.
142, 148, 160, 178, ?, 232
15.975 ×27.825 + (76.01)² + 12.98×18.426 = ?+ (79.09)²
