CA, along with Bcom, will be a great career option. I will suggest you go for coaching as there will be immense peer-learning opportunity involved.

1369 square root solution


Show previous answers

Srinjini Agrawal replied | 9 hrs ago

37 is the square root of 1369. You can find the same by the below method:
1369 lies between 900 and 1600, i.e. 30^2 & 40^2
Since number ends in 9, it can either be 33^2 or 37^2
The number is closer to 1600 hence it can only be 37^2
Alternatively, it can be found by Long Divison Method.

you can do it by grouping two digits together form right like in this case 1369. now start division
step 1: choose the number such that its square is close to our left end pair (here 13)
      04 69
   step 2 : Now multiplie the divisor with 2 (3 *2 =6)
choose another number (here 7), to place on the right side of the multiplied divisor (here 6) such that both the digits combined and multiplied with the chosen number will give either the exact value (here 496) or close to our required value.
so our square root of 1369 is our first digit 3 and our second digit 7 =37
for quick calculations follow this method
  we know the square of 30 =900
 and the square of 40 =1600
so the square of some number between 30 to 40 will be 1369
Now check the middle number, i.e. 35
sq of 35 =1225
that means our required number lies between 35 to 40
Now go for unit digit. Our unit digit is 9, which is given by 3 or 7 only when squared.
From 35 to 40 only 37 square will be 9 as a unit digit.
Our answer is 37.


Can someone suggest me a good brand and model of an acoustic guitar for beginners?

Budget is the factor Abhishek. You can learn by owning a guitar; costs ₹3000 or ₹45000. Basically on low ranges, you would only get local brand guitars like, "Givson", "Yamaha", "Hobson", "Signature" etc. These guitars are made out of only ply.
If you are looking for an imported guitar, that shall cost you near about ₹5000-₹5,500. That's the starting range, and you would get models made out of "Wood".
I would suggest going for an imported one for longevity and quality. Some of the brands are as follows.
Pluto, Granada, Heartz, gb&a, Cort, Ibanez, Epiphone, Fender, Ibanez, Yamaha etc.

YAMAHA F310 is probably the best acoustic guitar that you can buy for a beginner. It is good enough for intermediate level as well.
