2.
Find the smallest number which is exactly divisible by all the numbers from 1 to 9.
3.
Find the sum of all the prime numbers between 10 and 20 and check whether that sum is divisible by all the single digit numbers.
4.
The traffic lights at three different road junctions change after every 40 seconds, 60 seconds and 72 seconds respectively. If they changed simultaneously together at 8 a.m at the junctions, at what time will they simultaneously change together again?
5.
What is the greatest possible volume of a vessel that can be used to measure exactly the volume of milk in cans (in full capacity) of 80 litres, 100 litres and 120 litres?
6.
Find the HCF and the LCM of the numbers 154, 198 and 286.
7.
The digits of the prime number 13 can be reversed to get another prime number 31. Find if any such pairs exist upto 100.
8.
The sum of any three odd natural numbers is odd. Justify this statement with an example.
9.
Write the smallest and the biggest three digit composite number.
10.
Write the smallest and the biggest two digit prime number.
1.
Given
No. of the floors = 108
Two lifts A and B starting from the ground floor, stop at every 3rd and 5th floors respectively.
= 3 \(\times\) 5 = 15
Therefore The lifts will stop at floors 15, 30, 45, 60, 75, 90 and 105.
2.
Given: numbers are 1 to 9.
Therefore the smallest number
= \(2 \times 2 \times 3 \times 3 \times 5 \times 7 \times 2\)
= 2520
3.
All the prime numbers between 10 and 20 are 11, 13, 17 and 19
sum = 11 + 13 + 17 + 19
= 60 - single digits ( 1 to 9 )
i) 60 is divisible by 1.
ii) 60 is divisible by 2.
iii) 60 is divisible by 3.
iv) 60 is divisible by 4.
v) 60 is divisible by 5.
vi) 60 is divisible by 6.
vii) 60 is not divisible by 7, 8 and 9.
Therefore the sum 60 is divisible by 1, 2, 3, 4, 5 and 6.
4.
Given: 40 seconds, 60 seconds and 72 seconds
LCM = \(2 \times 2 \times 5 \times 2 \times 3 \times 3\) = 360 seconds
Also given, they changed simultaneously together at 8 a.m.
Therefore 360 seconds = 6 min
⇒ 1 hour = 60 min
Therefore 8 a.m. + 6 min = 8.00 + 0.06
Time = 8.06 a.m.
After 360 seconds, therefore 8.06 a.m. will they simultaneously change together again.
5.
Given: 80 litres, 100 litres and 120 litres.
Greatest possible volume of a vessel.
Therefore HCF = 5 \(\times\) 2 \(\times\) 2 = 20
Therefore the greatest possible volume of a vessel = 20 l milk.
6.
i) LCM
Therefore LCM = \(2 \times 11 \times 7 \times 9 \times 13\) = 18018
ii) HCF
Therefore HCF = 2 \(\times\) 11 = 22
7.
The given prime number 13 can be reversed
to get another prime number 31.
Similarly, other any such pairs are (17, 71), (37, 73) and (79, 97)
8.
Let 3 odd natural numbers are 3, 7 and 9.
Sum = 3 + 7 + 9 = 19 is odd.
This statement is true.
9.
The smallest 3 digit composite number = 100
The biggest three digit composite number = 999
10.
The Smallest two digit prime number = 11
The Biggest two digit prime number = 97
