Question

digits exceeds the given number by 9. Find the original number.
6. In a 3-digit number, the tens digit is thrice the units digit and the hundreds digt Solution
Adding (1) and (11),
- 2x and the units die
Finde
Also,
Putting b = 5 in (1), we get: a +5
the original number = (10a + b) = 1103
In a 3-digit number, the hundreds digit is twice the tens digit while
is thrice the tens digit. Also, the sum of its digits is 18. Find the number
Let the tens digit be x. Then, the hundreds digit
2x + x + 3x = 18 6x = 18 X = 3.
hundreds digit = (2x 3) = 6, tens digit = 3 and units digit = (3x3)
Hence, the required number = (100 x 6+10x3 + 9) = 639.

Answer 1

Answer:

Ohm's law, description of the relationship between current, voltage, and resistance. The amount of steady current through a large number of materials is directly proportional to the potential difference, or voltage, across the materials.

Step-by-step explanation:

digits exceeds the given number by 9. Find the original number.

6. In a 3-digit number, the tens digit is thrice the units digit and the hundreds digt Solution

Adding (1) and (11),

- 2x and the units die

Finde

Also,

Putting b = 5 in (1), we get: a +5

the original number = (10a + b) = 1103

In a 3-digit number, the hundreds digit is twice the tens digit while

is thrice the tens digit. Also, the sum of its digits is 18. Find the number

Let the tens digit be x. Then, the hundreds digit

2x + x + 3x = 18 6x = 18 X = 3.

hundreds digit = (2x 3) = 6, tens digit = 3 and units digit = (3x3)

Hence, the required number = (100 x 6+10x3 + 9) = 639.
