Directions: The following questions are based on the three digit numbers given below:

972     938     895     863     692     536
 
1
If the sum of the first and the last digits of a number is even then change the middle digit of that number to 8 and if the sum of the first and the last digits of a number is odd then interchange the first and last digit then which of the following numbers thus formed will be lowest?
» Explain it
E
The given sequence:

972  938  895  863  692  536

Applying above conditions in the given sequence, we get:

279  839  598  368  286  635

The lowest number is 279.

Hence, the correct answer is option E.
 
2
What would be the third highest number obtained after subtracting 2 from every odd digit of the given sequence and adding 1 to every even digits of the given sequence and then interchanging the first digit with third digit?
» Explain it
C
The given sequence:

972 938 895 863 692 536

Applying above conditions in the given sequence, we get:

357 917 379 179 377 713

The third highest number is 379.

Hence, the correct answer is option C.

 
3
If all the digits are arranged in decreasing order from left to right within the numbers and then the numbers thus formed are arranged in increasing order from right to left. Then which of the following numbers will be second from left end?
» Explain it
B
The given sequence:

972 938 895 863 692 536

Applying above conditions in the given sequence, we get:

985 983 972 962 863 653

The second number from left end is 983.

Hence, the correct answer is option B.

 
4
If the sum of the highest and the lowest number is divided by the difference of the third highest and the third lowest number and the resultant is then multiplied by 8, which of the following numbers will we finally get?
» Explain it
D
The given sequence:

972 938 895 863 692 536

Applying above conditions in the given sequence, we get:

Sum of the highest and the lowest number is 972 + 536 = 1508

Difference of the third highest and the third lowest number is 895 – 863 = 32 (1508/32)×8 = 377

The number we get is 377

Hence, the correct answer is option D.
 
5
If all the digits within the number are multiplied to each other then how many numbers thus formed will be less than 200?
» Explain it
D
The given sequence:

972     938      895     863    692    536

Applying above conditions in the given sequence, we get:

126      216      360     144     108    90

There four such number that are less than 200.

Hence, the correct answer is option D.
