The natural numbers below 660 which are divisible by 5 and 11 but not by 3 are?
Your Answer : (Not Answered)
Correct Answer : A
If the number is divisible by 5 and 11 it must be divisible by 55.
The numbers are less than 660.
Hence, dividing 659 by 55 gives the number of multiples of 55 = 11 (ignoring fraction part).
The 11 multiples of 55 which are less than 560, but of these 11 multiples some can be multiples of 3.
The numbers of such, multiples is the quotient of 11 by 3.
Quotient of 11/3=3.
Out of 11 multiples of 55, 3 are multiples of 3.
Hence, numbers less than 660 and divisible by 5 and 11 but not by 3=11−3=8
A is three times as old as B. C was twice-as old as A four years ago. In four years' time, A will be 31. What are the present ages of B and C ?
Your Answer : (Not Answered)
Correct Answer : C
Let the age of A = \(A\), B = \(B\) and C = \(C\)
From given,
\(A = 3B\)
4 years ago,
\(A + 4 = 31\)
\(\Rightarrow A=27\)
sub in above \(B\) , we get \(B\) = 9
\(C = 2(27 - 4) + 4 = 46 + 4 = 50 \)
Hence B = 9years and C = 50years.
