Question

By sutiable arrangement find the sum :--
834,723,66,277

Answer 1

Answer:

(834+66) + (723+277)

= 900 + 1000

= 1900

Step by step explanation:

Check the digits in the ones place of the numbers.

4, 3, 6, 7 respectively

And, we know that,

6 + 4 = 10 and 3 + 7 = 10

So if we arrange the numbers as

(834+66) + (723+277)

it will be much suitable to calculate the sum than arranging it in any other way.

Try arranging it in other ways and see for yourself which way is more suitable.

Hope this helped :)
