Question

Round off to the nearest lakhs: The given number is 38, 65, 62, 048
(a) 38, 68, 60, 000
(b) 38, 65, 600
(c) 38, 65, 00, 000
(d) 38, 66, 00, 000

Answer 1

Hint: We have to round off the given number to the nearest lakhs, so we are going to look at the numbers that are after the lakhs, if the number is greater than 50 thousand then we will increase the lakhs by 1 and if it is less than 50 thousand then we will replace all the numbers after lakhs with 0.

Complete step-by-step answer:

Let’s first look at the given number and will try to find the thousands place in that number,
38, 65, 62, 048

It has 65 lakhs and 62 thousands.

Now as per the rules of rounding off to the nearest lakhs, if the number in the thousand place are greater than 50 then we will increase the number in lakhs by 1.

Let’s see,

The number in this question has 62 in thousands which is greater than 50, and hence we will increase the number in lakhs by 1.

So, the number in lakhs will become 65 + 1 = 66

Hence, the answer we get after rounding off is 38, 66, 00, 000.

Hence option (d) is correct.

Note: In this question students might get confused about how to round off to lakhs, so one can expand the numbers in the powers of 10, like unit place, tens place, hundreds place etc. And one can find what number is in lakhs and thousands and then can perform the similar method after that.
