Question

Find the sum of the place values of 7 in 974 .673 ? pls tell me the answer ​

Answer 1

Answer:

Complete step by step answer:

Now consider question a)

Now first consider the number 691.

Here we know that 9 is in tens place. Hence its place value is 90

Now the face value is 9. Hence the sum of face value and place value is 9 + 90 = 99.

Now consider question b)

We know that Arun interchanges tens and hundreds of digits of the number 673.

Now here tens digit is 7 and hundreds digit is 6.

Hence after interchanging tens digit is 6 and hundreds digit is 7.

Hence the number obtained is 763.

Now let us take the difference of obtained number and original number

Hence we get 763 – 673 = 90

Hence the number is increased by 90.

Now consider question c)

The given sequence is 5, 8, 11, 14, 17….

Now in this sequence let us check the difference of consecutive terms

8 – 5 = 3

11 – 8 = 3

14 – 11 = 3

17 – 14 = 2

Hence we can say that the common difference is 3.

Now let x be the next number

Hence we get x – 17 = 3.

Which means x = 17 + 3 = 20

Hence the next number in the sequence is 20.

Now consider our last option d)

Even numbers are numbers which are divisible by 2.

Now let us first list all the numbers between 40 to 60.

41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59.

Now if the unit's place of number is divisible by 2 then the number is divisible by 2.

Hence the numbers with units place 0, 2, 4, 6, 8 are divisible by 2.

Hence in between 40 to 60, the numbers which are divisible by 2 are.

42, 44, 46, 48, 50, 52, 54, 56, 58.

Hence there are total 9 even numbers between 40 and 60
