Answer 2

Step-by-step explanation:

To find the least 5-digit number which leaves a remainder 9 in each case when they are divided by 12,40 and 75

Let us see factors for the given numbers 12,40,75

For 12 prime factors are 12:2

2

×3

for 40 prime factors are 40:=2

3

×5

For 75 prime factors are 75=5

2

×3

So, now let us find out the greatest four digit number that which is exactly divisible by given numbers

∴ the greatest four digit number divisible by given numbers =9999

So, LCM of the given numbers is LCM=2

3

×3×5

2

=600

So, to find out the greatest four digit divisible by given numbers ⇒ 9999−remainder

⇒ 9999−399=9600

in order to get 5 digit number exactly divisible by the given numbers , we get

9600+600=10200

but given in the question that when 5-digit number is divided by the given numbers we get a remainder 9
