QUESTION: 1

### The ratio of the present ages of Sushma and Karishma is 6 : 7 respectively. The ratio of their ages 8 years hence would be 8 : 9 respectively. What would be the respective ratio of their ages after 12 years?

Solution:

Let the present ages of Sushama and Karishma be 6x and 7x respectively. or 56x + 64 = 54x + 72
x = 8/2 = 4
Required ratio QUESTION: 2

### The solution of the equation x-y = 0.9 and 11/2 (x+y)=1 is

Solution:

The given system of equation is
x - y = 0.9 = 9/10 ...(1)
and 11 /2(x + y) = 1
⇒ x + y = 11/2 ...(2)
Adding (1) and (2), we get
2x = 9/10 + 11/2
⇒ 2x = 9 + 55/10 = 64/10
⇒ x = 32/10 = 3.2
When x = 3.2, we get
3.2 - y = 0.9 (using(1))
⇒ y = 3.2 - 0.9 = 2.3
Thus, the solution of system of equation is x = 3.2 and y = 2.3

Two wires have their lengths, diameters and resistivities, all in the ratio of 1 : 2. If the resistance of the thinner wire is 10 ohms, the resistance of the thicker wire is

Solution:

Resistance is directly proportional to the length of the wire, its resistivity and inversely proportional to the cross-sectional area.
WIRE I
Let the length = L
Resistivity = R
Diameter = D
∴ Total Resistance ∝ L x R/ D2
WIRE II
Length = 2L
Resistivity = 2R
Diameter = 2D
∴ Total Resistance = 2L x 2R / 2D x 2D = LR/D2
∴ WIRE I : WIRE II = LR/D2 : LR/D2 = 1 : 1
i.e. Resistance of WIRE ZB is also 10Ω

QUESTION: 64

Two trains 100 metres and 120 metres long are running in the same direction with speeds of 72 km/hr and 54 km/hr. In how much time will the first train cross the second?

Solution:

Trains are moving in the same direction
So the relative speed with which the y pass each other = (72 - 54) km/hr = 18 km/hr
distance covered = sum of the lengths of trains
= 100 + 120 = 220m = 220/1000 km = 11/50 km
Required time = 11/50 x 1/18 x 3600 = 44 sec

A certain sum was put at a certain rate of interest for 3 yrs. Had it been put at 2% higher rate, it would have fetched Rs 72 more. Find the sum.

Solution:

At 2% more rate, the increase in SI for 3 years = Rs 72 (given)
So at 2% more rate the increase in SI for 1 year = 72/3 = Rs 24
i.e., Rs 24 is 2% of the invested sum
So 1% of the invested sum = 24/2 = 12
Therefore, the invested sum
= 12 x 100 = Rs 1200

Let PQ = 64 km A man starts from P and walks 32 km on first day, on second day he walks only 16 km, on third day he walks 8 km, on fourth day he walks just half, i.e. 4 km. He will reach Q in

Solution:

Distance between PQ = 64 km
Distance covered on the 1st day = 64/2 = 32 km
Distance covered on the 2nd day = 32/2 = 16 km
Like wise Total distance covered = 32 + 16 + 8 + 4 + ..........
This is an infinite geometric series whose first term is 32 and common ratio = 1/2
∴ Sum of the infinite series = a/1 - r
Where a is the first term and r common ratio = 32/1/2 = 64
Hence the man will never reach Q
