Sum of the digits of a number of two digits is 8e interchange the digits, we see that thebetween the numbers is 18. Find theoriginal number.

Answer»

Ans :- Let us assume the digits of a number as 'x' and 'y'. Since it is a 2 digit number, we have one's place and ten's place. ( i.e., The place value of one digit is multiple of 10 and the place value of other digit is one.) I assume you know the difference between place value and face value.

Now going to the problem,

Sum of two digits is 8. => x +y=8→A

Diff between number and its reverse:

=> (10x+y)-(10y+x)=18

=>9x-9y=18

=> x-y=(18/9)=2→B

Solving A and B

x+y=8

x-y=2

=>2x=10=>x=5. Hence y = 3.

Hence the required number is53

answer is 35

Find the least number of five digits which on dividing by 4,12,20 and 24 leaves remainder 3 in each case

Answer»

Least 5 digit number = 10000.

LCM(4,12,20,24) = 120

Dividing 10000 by 120 leaves a remainder 40 , Subtract 40 from 10000 = 9960

So this means 9960 is divisible by 120.

9960 + 120 = 10080.

To find the number which leaves remainder 3, we have to add 3 to 10080.

10080 + 3 = 10083.

23.

22 If N+5 leaves the remainder 3, then what might be the value of one's digit of N?

Answer»

Let k be an even number:

k=2x

Now, N= 5*2x+3=> N=10x+3

So, N leaves a remainder 3 when divided by 10,So, the ones digit is 3.

So, the ones digit is either 3 or 8.

3lole 0y8is6 divisible by 8? Explain wthxamples.Write the smallest 4-digit number that is divisible by 2,3,4,5 and63420Multiples

Answer»

The smallest 4 digit number divisible by 2,3,4,5 is 1020.The number divisible by 2,3,4,5 and 6 has to be divisible by their LCM which is 60.

Now the smallest 4 digit number is 1000. On dividing it by 60 we get 40 as remainder so subtracting 40 from 1000 gives a number which is divisible by 60 So 960 is divisible by 60. The next number divisible by 60 is 960+60 = 1020.

960 is a 3 digit number so 1020 is the smallest 4 digit number divisible By 60 and hence divisible by 2,3,4,5 and 6.
