7.

If all the digits in the given numbers are written in the reverse order, then if we divide the number by 11 which of the following number will yield highest remainder   

   A.) 498
   B.) 397
   C.) 524
   D.) 279

Answer: Option 'C'

If all the digits in the given numbers are written in the reverse order,then if we divide the number by 11 we get,
498 = 894 / 11 => Quotient = 81.2 Remainder = 3
397 =793 / 11 => Quotient = 72.09 Remainder = 1
279 = 972 / 11 => Quotient = 88.36, Remainder = 4
524 = 425 / 11 => Quotient = 38.63,Remainder = 7
716 = 617 / 11 => Quotient = 56.09 ,Remainder = 1
Highest remainder = 7 , 524 is correct answer.

8.

In the given numbers if the digit in the hundredth place is removed, which of the following numbers will be maximum  

   A.) 826
   B.) 575

749 = 49
575 = 75
486 = 86
86 is maximum number , so 486 is correct answer.

9.

Which of the following number yields maximum remainder, when it is divided by 13 ?

   B.) 383
   C.) 466
   D.) 525

Answer: Option 'C'

Given
Following numbers, when it is divided by 13 , which yields maximum remainder
419 => 419 / 13 => Quotient = 32.23, Remainder = 3
383 => 383 / 13 => Quotient = 29.46 ,Remainder = 6
525 => 525 / 13 => Quotient = 40.3 ,Remainder = 5
466 => 466 / 13 => Quotient =35.84,Remainder = 11
281 => 281 / 13 => Quotient = 21.6 ,Remainder = 8
11 is maximum remainder , 466 is correct answer.

10.

In the given numbers if the digit in the hundredth place is removed, which of the following numbers will be maximum? 

   A.) 485
   B.) 351
   C.) 517
