Playing with Numbers
The least number which when divided by 6, 15 and 18 leaves a remainder 5 in each case is

a) 100
b) 95
c) 90
d) 80



Answer
Solution
Correct Answer Is : 95
Solution Is : LCM of 6, 15 and 18 = 90 Now, the required least number that leaves remainder 5 in each case = 90 + 5 = 95
The HCF and LCM of the numbers 30 and 45 are in the ratio

a) 2:3
b) 6:1
c) 7:2
d) 7:5



Answer
Solution
Correct Answer Is : 6:1
Solution Is : Factors of 30 = 2 x 3 x 5 Factors of 45 = 3 x 3 x 5 LCM of 30 and 45 = 2 x 3 x 3 x 5 = 90 and HCF of 30 and 45 = 3 x 5 = 15 Required ratio of LCM and HCF = 90 : 15 = 6 : 1
The HCF of two numbers is 16 and their LCM is 160. If one of the number is 80, then the other number is

a) 20
b) 28
c) 32
d) 38



Answer
Solution
Correct Answer Is : 32
Solution Is : Let the other number be n. We know that, Product of the numbers = HCF x LCM Therefore, 80 x n = 16 x 160 or, n = 32
The number, divisible by 9, is

a) 327
b) 3527
c) 8253
d) 8564



Answer
Solution
Correct Answer Is : 8253
Solution Is : If the sum of the digits of a number is divisible by 9, then the number itself is divisible by 9. The sum of the digits of 8253 = 8 + 2 + 5 + 3 = 18, divisible by 9.
The number, divisible by 5, is

a) 3527
b) 3614
c) 4399
d) 37595



Answer
Solution
Correct Answer Is : 37595
Solution Is : A number which has either 0 or 5 in its ones place is divisible by 5. Since, the number 37595 has 5 is in ones place thus it is divisible by 5.
Sum of two prime numbers (except 2) is always

a) Divisible by 2.
b) Divisible by 4.
c) Odd
d) Prime



Answer
Solution
Correct Answer Is : Divisible by 2.
Solution Is : We know that all the prime numbers except 2 like 3, 5, 7, 11, and so on are odd numbers. So, the sum of any two prime numbers other than 2 is an even number. For example, 3 + 5 = 8 and 7 + 11 = 18. An even number is always divisible by 2.
All the factors of 63 are

a) 1, 3, 7, 9, 21 and 63.
b) 3, 7, 9, 21 and 63.
c) 1, 3, 7, 9 and 21.
d) 3, 7, 9 and 21.



Answer
Solution
Correct Answer Is : 1, 3, 7, 9, 21 and 63.
Solution Is : A factor of a number is an exact divisor of that number. Factors of 63 are 1, 3, 7, 9, 21 and 63.
The numbers other than 1, with only factors namely 1 and the number itself, are known as

a) Composite number
b) Even number
