Test: Number System - 1 - Grade 4 MCQ

The number that is 1000 more than 69,090 is calculated as:

69,090+1,000=70,090

So the correct answer is a) 70,090.

Place value of 5 in 5,43,621

= 5 × 1,00,000

= 5,00,000

= 5 lakh

By adding one to the largest five-digit number, we get 1,00,000 which is the smallest six-digit number.

Smallest 6 digit number = 1,00,000

We have 300000 + 20000 + 4000 + 200 + 2

The ones period consists of the digits in the hundreds, tens, and ones places.

• The first period, called ones period, is formed with the first three digits of the number.
• The second period, called thousands period, is formed with the next two digits of the number.
• The third period, called lakhs period, is formed with the next two digits of the number.

• The ones period consists of the digits in the hundreds, tens, and ones places.
• The thousands period consists of the three places to the left of the ones period.
• The millions period consists of the three places to the left of the thousands period.

Apart from option d, all others are used to define place value to a number.

We use comma to separate the periods.

4,37,283 is a 6 digit number.
