Answer 1

Given:

The numbers are 0,4,5,6,9,7,1

To find:

(a) Write a number between 5 and 6 million.

(b) Write a number greater than 80 lakhs

(c) Write the largest and the smallest 7-digit numbers without repeating the digits.

(d) Write the largest 7-digit number with 0 at the thousands place.

Solution:

a) 5,647,910

Reason: Millions come in international number system. The question says to write any number between 5 to 6 million. Thus, you can place any digit in any place except 5 which has to be in millions place to have the number between 5 to 6 million.

b) 91,47,065

Reason: We are asked to write any number greater than 80 lakhs, thus we need to start the number with 9 and can put any digit afterwards.

c) Largest : 97,65,410

Largest : 97,65,410 Smallest : 10,45,679

Reason: For finding the largest we can simply put the numbers in descending order and for the smallest in ascending order but remember to insert 0 in the second place otherwise we will have 6 digit number.

d) 97,60,541

Reason: For largest number arrange the numbers in descending order and then place 0 in thousands place and shift the numbers from there backwards.
