Hello,

Answer of challenge question 5

3 ab * 61=19947

First of all, see  the digit in the units place of the answer.It is 7.

Applying “Last by Last”sutra,we get b=7.

Now,

3 a*7* 61=19947

21a*61= 19947

Applying digit sums,

digit sum of 19947=3(casting out 9’s)

Numbers                            Digit sums

21a                                        3+a

61 *                                        7 *

——–                                ———

19947                                   3

In the digit sums column,

(3+a) * 7 = 3

21 * 7a =3

again, applying digit sums,

3 * 7a=3

for this to be true, 7a=9,implies a=2

so the smudged digits are b=7 and a=2

327 * 61=19947

Thanks

Hello,

Anwer to challenge question 6    234*111=???

unit digit  : 4(same digit)

digit in ten’s  place : 3+4=7

digit in hudredth’s place: 2+3+4=9

digit in Thousanth’s place: 2+3=5

digit in ten-thousandth’s place : 2

so answer will be 25973.If there is any carry over,we have to add them .

we can do it from left to right also.Don”t forget to add the carry overs.

so in general, if pqr is a 3 digit number.

So we need to find pqr*111=?

ans will be:

p (p+q) (p+q+r) (q+r) r (taking into consideration the carry overs).

similarly, 854*111 =94794(in this case ,we have carry overs,we need to take those into account).

Thanks

Hello,

Bar numbers in lesson 11(week 3) is a useful concept with many advantages.The bar notation which we used ,were to show repeating numbers after the decimal  point like 3.3333……..=3.(3) i.e 3 point bar 3.

It was used to show the number pattern which goes on forever(infinity).

I had an impression that Bar notation can only be used if the number is the decimal number.

But now I understand that apart from being used in decimal numbers only,it has many more advantages.

Thanks
