ARRANGE NUMBER IN DESCENDING ORDER

Ans.)  We can observe that the given number series as follows 24, 36, 44, 55, 67. If we start count from 1, then we find the number series would be 1, 2, 3,…………, 22, 23, 24, 25, 26,………....34, 35, 36, 37, 38, ..……….., 42, 43, 44, 45, 46,…………, 52, 53, 54, 55, 56, 57,….………., 64, 65, 66, 67, 68. From, the obtained number series count starting from 1 and we can observe that given numbers comes in following sequence 24, 36, 44, 55, 67 and in this sequence we can observe here 24 comes first so 24 is the smallest number, and here 67 comes last in this sequence so, 67 is the biggest number among all the given numbers. So if we arrange the number in descending order (decreasing) then the number series would be 67, 55, 44, 36, 24. (Ans.)

2)  25, 89, 63, 75, 37

Ans.)  We can observe that the given number series as follows 25, 89, 63, 75, 37. If we start count from 1, then we find the number series would be 1, 2, 3,…………, 22, 23, 24, 25, 26,………....34, 35, 36, 37, 38, ..……….., 42, 43, 44, 45, 46,…………, 52, 53, 54, 55, 56, 57,….………., 62, 63, 64, 65,………, 72, 73, 74, 75, 76, 77,………….., 86, 87, 88, 89, 90, 91. From, the obtained number series count starting from 1 and we can observe that given numbers comes in following sequence 25, 37, 63, 75, 89, and in this sequence we can observe here 25 comes first so 25 is the smallest number, and here 89 comes last in this sequence so, 89 is the biggest number among all the given numbers. So if we arrange the number in descending order (decreasing) then the number series would be 89, 75, 63, 37, 25. (Ans.)

3)  18, 62, 46, 28, 86, 77     

Ans.)  We can observe that the given number series as follows 18, 62, 46, 28, 82, 77. If we start count from 1, then we find the number series would be 1, 2, 3,…………, 15, 16, 17, 18, 19,………, 26, 27, 28, 29, 30,………...., 36, 37, 38, ..……….., 44, 45, 46, 47, 48,…………, 54, 55, 56, 57,….………., 60, 61, 62, 63, 64, 65,…………, 75, 76, 77, 78,………….., 84, 85, 86, 87, 88. From, the obtained number series count starting from 1 and we can observe that given numbers comes in following sequence 18, 28, 46, 62, 77, 86, and in this sequence we can observe here 18 comes first so 18 is the smallest number, and here 86 comes last in this sequence so, 86 is the biggest number among all the given numbers. So if we arrange the number in descending order (decreasing) then the number series would be 86, 77, 62, 46, 28, 18.    (Ans.)
