In a five-digit number, the digit at the hundreds place is double of the digit at the unit place and the digit at ten thousand place is double of the digit at the hundreds place. The digit at tens place is the smallest odd prime number and the digit at thousands place is three times the unit digit. If the digit at the unit place is the even prime number, then the number is Correct Answer 86432

Given:

The digit at the hundreds place is double of the digit at the unit place

The digit at ten thousand place is double of the digit at the hundreds place

The digit at tens place is the smallest odd prime number

the digit at thousands place is three times the unit digit

The digit at the unit place is the even prime number

Concept used:

Prime number: A number that can be divided exactly by 1 and itself. For example 2, 3, 5 etc

2 is the even prime number and 3 is the smallest odd prime number 

Calculation:

Unit digit = 2

The digit at the ten's place = 3

Digit at the thousand place = 3 × unit digit = 3 × 2 = 6

The digit at the hundreds place = 2 × unit digit = 2 × 2 = 4

The digit at the ten thousands place = 2 × hundreds place = 2 × 4 = 8

Number = 86432

∴ The required number is 86432
