RRB ALP & Technician Mock Test (English) - 4 - Question 2

### The ratio between the present ages of A and B is 4:5. If the difference between their present ages is 8 yrs, what is the sum of their present ages?

Detailed Solution for RRB ALP & Technician Mock Test (English) - 4 - Question 2

The ratio between the present ages of A and B is 4:5.
A/B = 4/5 ⇒ 5A = 4B ⇒ 5A - 4B = 0 .....(1)
If the difference between their present ages is 8 yrs
A - B = 8 .....(2)
multiplying 5 both sides in equation(2)
⇒ 5(A - B) = 40
⇒ 5A - 5B = 40
Subtracting equation (1) from equation (2) we get
B = 40
5A = 4B
⇒ 5A = 4 x 40 = 160
⇒ A = 160/5 = 32
Sum of present ages = 40 + 32 = 72

RRB ALP & Technician Mock Test (English) - 4 - Question 49
A number when divided successively by 4 and 5 leaves remainder 1 and 4 respectively. When it is successively divided by 5 and 4 the respective remainders will be
Detailed Solution for RRB ALP & Technician Mock Test (English) - 4 - Question 49 When dividing a positive integer n by another positive integer D (divider), we obtain a quotient Q, which is a non-negative integer and a remainder R, which is an integer such that 0 ≤ R < D. We can write n = DQ + R.
When dividing our number n by 4 we obtain a remainder of 1, so, if the quotient is some integer Q, we can write n = 4Q + 1.
successively divide means quotient Q is divide by 5.
Now, dividing Q by 5, we obtain another quotient say q and remainder 4, thus we can write Q = 5q + 4.
It follows that n = 4(5q + 4) + 1 = 20q + 17.
Since n = 20q + 17 = 5(4q + 3) + 2, it means that when dividing n by 5 first, we get a quotient 4q + 3 and remainder 2.
Then dividing 4q + 3 by 4 we obviously obtain a remainder of 3.
Hence remainder is 2,3 by dividing the no by 5,4.
