Answer 2

Given:

A number 7000,

To Find:

The number of Tens added to 7000 such that the value becomes 70000.

Solution:

The given problem can be solved using simple algebra.

1. The given initial value is 7000. Let a total number of x Tens be added to 7000 to become 70000.

2. Hence, the addition of 7000 and Ten ( repeated x times ) will be 70000. The algebraic equation can be written as,

=> 7000 + 10x = 70000,

=> 10 x = 70000 - 7000,

=> 10x = 63000,

=> x = 63000/10,

=> x = 6300.

3. A total of 6300 tens are to be added.

Therefore, 6300 tens must be added to make 7000 as 70000. Option C is the correct answer.
