**How to Solve**

- Take 7 Common and Replace all 7 with 1,

7(0.1 + 0.11 + 0.111 + 0.1111 + 0.11111 + 0.111111) - Count number of digits after the decimal place.

i.e, 0.1=1(digit), 0.11=2(digit), 0.111=3(digit), 0.1111=4(digit), 0.11111=5(digit), 0.111111=6(digit). - Write down all digits together but in reverse order like, 0.654321
- Multiply 7×0.654321 = 4.580247
- Now Multiply the Whole number with the total numbers present in the group.

i.e, 7 x 6 = 42 - Now Add both the results together ( 4.580247 + 42 ) =
**46.580247**.

- Take 3 Common and Replace all 3 with 1,

3(0.1 + 0.11 + 0.111 + 0.1111) - Count number of digits after the decimal place.

i.e, 0.1=1(digit), 0.11=2(digit), 0.111=3(digit), 0.1111=4(digit). - Write down all digits together but in reverse order like, 0.4321
- Multiply 3×0.4321 = 1.2963
- Now Multiply the Whole number with the total numbers present in the group.

i.e, 3 x 4 = 12 - Now Add both the results together ( 1.2963 + 12 ) =
**13.2963**.

Example 3:

7.7+7.77+7.777+7.7777+7.77777+7.777777

The result of the addition is 7.7+7.77+7.777+7.7777+7.77777+7.777777 = 54.3580247.

Shortcut Tricks

Step 1: At First we can calculate the Decimal number 7 ( 0.7654321 ) = 5.3580247

Step 2: In Step 2 we can calculate the Whole numbers that is maximum number 7 digits is

= 7+7+7+7+7+7+7 So, 7 x 7 = 49

Step 3: Now we can add both result of step 1 and Step 2 = ( 49 + 5.3580247 ) = 54.3580247.

In the above sum question is in wrong format add 7.7777777 to above quation

Thank u so much for valuable feedback priya , please recheck the problem

Thank u

Hello mam,upar jo ans dia h wo sahi h,aapne trick glt smjhi h ,basics se chech krke dekh lo

sir, not mam and thank u

The correct answer of above que is 46.580247

there are only six 7’s are there. So, 7×6=42. and (7×0.654321)=4.580247.

So, 42+4.580247=46.580247 is correct
