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?

Solution:

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

The minute hand of clock is √21 cm long. The area described by a minute hand on the face of the clock between 7 am and 7.05 am is

Solution:

Given that length of minute hand of clock is √21 cm

Angle described by the minute hand in 60 minutes = 360^{o}

Angle described by the minute hand in 5 minutes = 360/60 x 5 = 30^{o}

We know that Area of sector = θ/360 x πr^{2}

= 30/360 x 22/7 x √21 x √21

= 11/2 = 5.5 cm^{2}

The HCF and LCM of two numbers are 12 and 72 respectively. If the sum of the two numbers is 60,then one of the two numbers will be

Solution:

H.C.F = 12, L.C.M = 72

Let one number be = x, then other number = 60 - x

Now, x x (60 - x) = 12 x 72

or 60x - x^{2} = 864

or x^{2} - 60x + 864 = 0

or (x - 36) (x - 24) = 0

or x = 36 , 24

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

Solution:
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.

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.
