Question

M is the largest number which when rounded off to the nearest hundred gives 63500. N is the smallest number which when rounded off to the nearest thousand gives 150000. What is the sum of M and N?

Answer 1

Answer:

1563049

Step-by-step explanation:

M = largest no. rounded to 63500

63550 rounded sum = 63600

Predecessor of 63550 = 63549

63549 rounded sum = 63500

Hence , M = 63549

Now,

N = smallest no. that when rounded off to nearest thousands gives 150000

14,99,500 when rounded to nearest thousands = 1500000

We know that ,

M = 63549

N= 1499500

63549 + 1499500

= 1563049

So , M+ N = 1563049

Answer 2

Answer:

The sum of M and N is 213049.

Explanation:

Rounding off means a number is made simpler by keeping its value intact but closer to the next number. It is done for whole numbers, and for decimals at various places of hundreds, tens, tenths, etc. Rounding off numbers is done to preserve the significant figures.

M is the largest number that is rounded off to the nearest thousand and gives 63500.

M = 63549 because it is rounded as 63500

similarly,

N is the smallest number which when rounded to the nearest thousand gives 150000.

N = 149500

sum of M and N = 63549 + 149500

sum = 213049
