The question is reprouduced here.Find the smallest 6 digit number Which is exactly divisible by 175smallest 6-digit number= 100000Hint: smallest 6-digit number is 1 with 0 written 5 times. Smallest 1-digit number is 1. Smallest 2-digit number is 10 , Smallest 3-digit number is 100 and so on . 100000/175
Quotient= 571
Remainder= 75
The required number = 100000-75
=99925 Hint: Remainder is the excess amount in the dividend (100000). Therefore this excess amount is deducted to get the exact dividend divisible by 175.

The question is reprouduced here.Find the largest 5 digit number Which is exactly divisible by 48largest 5-digit number= 99999Hint: largest 5-digit number is 9 written 5 times. Similarly largest 1-digit number is 9. Similarly largest 2-digit number is 99 and so on . 99999/48
Quotient= 2083
Remainder= 15
The required number = 99999-15
=99984 Hint: Remainder is the excess amount in the dividend (99999). Therefore this excess amount is deducted to get the exact dividend divisible by 48.

1. Write all possible numbers using the digits 3,6 and 8 without repeating of digits. Solution:
The numbers are: 3 at unit place: 863,683Hint: keep 3 at unit place and interchange the position of 8 and 6 6 at unit place:836, 386 Hint: keep 6 at unit place and interchange the position of 8 and 3 8 at unit place:638,368 Hint: keep 8 at unit place and interchange the position of 6 and 3 Question: Do it yourself for 2,4 and 9 2. How many whole numbers have two digits. Solution: The two digits whole numbers are from 10 to 99. e.g. 10,11,12......99.
Therefore the two digit numbers= 99-(10-1)
=99-9
=90 Note:Its general formula is : For two digits number = two digits highest number-(two digits lowest number-1)
3. How many whole numbers have three digits. Solution: The two digits whole numbers are from 100 to 999. e.g. 100,101,102......999.
We will apply the same formula by changing the numbers of digits only.
Therefore the three digit numbers= 999-(100-1)
=999-99
=900
Used formula is :thre…

4. Ramesh has enough money for 6 weeks if he spends Rs 1400 per week during summer vacation. How long will the money last if he spends Rs 1050 per week? Solution( By Unitary Method) : Here we have to find out nos. of weeks. Therefore we will keep the week at right side in the statement. &#x2235 By spending Rs 1400 per week the money lasts for 6 weeks. ∴ By spending Re 1 per week the money lasts for 6x1400 weeks.Explanation: For Re 1 per week spending the money will lasts for more numbers of weeks. . Therefore multiplication has been done. ∴ By spending Re 1050 per week the money will last for (6x1400)/1050 weeks. Explanation:For Rs 1050 per week spending, the money will lasts for less numbers of weeks in comparison to previous spending of Re 1 per week. Therefore division has been done.= 8400/1050 = 8 weeks Ans.

3. Eight people eat a stock of food in 30 days. How many people will consume the stock of food in 20 days? Solution( By Unitary Method) : Here we have to find out nos. of people. Therefore we will keep the people at right side in the statement. &#x2235 In 30 days a stock of food is eaten by 8 people. ∴ In 1 day same stock of food will be eaten by 30x8 people. Explanation: For 1 day more nos. of people will be needed to eat the same stock of food. Therefore multiplication has been done. ∴ In 20 days same stock of food will be eaten by (30x8)/20 people. Explanation: For 20 days lesser nos. of people will be needed to eat the same stock of food. Therefore division has been done.,/p>= 240/20 = 12 people Ans.

2. if 20 men can complete a job in 4 days. How many men will be required to finish the work in 40 days?
Solution:Suppose x men will be required to complete the job in 40 days &#x2235 To complete a job in 4 days the required men are 20 .∴ To complete the job in 1 day the required men are 20x4 . ( explanation: in 1 day more men will be needed to complete the same job, therefore for more men multiplication has been done.)∴ To complete the job in 40 days the required men are (20x4)/40 . explanation:lesser number of men will be needed to complete the job in 40 days in comparison to one day. Therefore division has been by 40= 80/40 = 2 men Ans.
