Answer 2

Numbers are 125 and 8.

Given:

The product of two positive integers, each of which is not divisible by 10, is equal to 1000.

To find:

The number which are satisfy this equation.

Explanation:

• This type of question can be solved by trial and error method.
• If last digit of the number zero then it will be divided by 10
• Hence we will chose first number which last digit will not come zero.
• So we consider multiple of 25 which is divisible by 1000.
• First we consider 25× 40 =1000
• So it cannot be satisfy given equation.
• Consider 125 × 8 = 1000
• So it can be satisfy our condition.
