QUESTION: 1

### The ratio between the ages of P and Q four yrs ago was 5 : 6. If the total of their ages at present is 52 yrs, what is the ratio of their present ages?

Solution: QUESTION: 2

### If x + y = 6 and 3x - y = 4, then x - y is equal to

Solution:

x + y = 6
⇒ y = 6 - x
Now, 3x - y = 4
or 3x - (6 - x) = 4
or 3x - 6 + x = 4
or 4x = 10 QUESTION: 3

### A train starts with full of passenges.At the first station,the train drops one-third of the passengers and takes in 96 more.At the next station,one half of the passengers on board get down while 12 new passengers get on board.The number of passengers now is 240.The number of passengers in the beginning was

Solution:

Let the number of passengers be x when the train started off
∴ At the first station, the number of passengers = x - x/3 + 96 = 2x/3 + 96
At the second station, the number of passengers = ( 2x/3 + 96) 1/2 + 12
At the third station, the number of passengers left = x/3 + 48 + 12 = 240
⇒ x/3 = 180
⇒ x = 540

QUESTION: 4
If (2x+3) and (x-1) are two factors of (2x2 + x)2 - 4(2x2 + x) + 3, then the remaining two factors are
Solution: (2x2 + x)2 - 4(2x2 + x) + 3
= 4x4 + x2 + 4x3 - 8x2 - 4x + 3
= 4x4 + 4x3 - 7x2 - 4x + 3
= 4x3 (x - 1) + 8x2 (x - 1) + x (x - 1) - 3 (x - 1)
= (x - 1) (4x3 + 8x2 + x - 3)
= (x - 1) [2x2 (2x + 3) + x(2x + 3) - 1(2x + 3)]
= (x - 1) (2x + 3) (2x2 + x - 1)
= (x - 1) (2x + 3) [2x2 + 2x - x - 1]
= (x - 1) (2x + 3) [(2x (x + 1)) - 1(x + 1)]
= (x - 1) (2x + 3) (x + 1) (2x - 1)

QUESTION: 7

Diagonals of a rhombus are in the ratio 3:4 and its area is 2400 cm2. Side of the rhombus is

Solution:

Let the diagonals of a rhombus are 3K and 4K. Then
Area of rhombus = 1/2 x product of diagonals
2400 = 1/2 x 3K x 4K
or 400 = K2
or K = 200
∴ The Diagonals are 60 cm and 80 cm
we know that, if a be side of the rhombus and AC and BD be its diagonals then
(AC)2 + (BD)2 = 4 x a2
or (60)2 + (80)2 = 4 x a2
or 3600 + 6400 = 4 x a2
or 10000 = 4a2
or 2500 = a2
or a = 50 cm

QUESTION: 8

A rectangular park is 200 by 150m. Two cross paths are to be made one parallel to the length and the other parallel to the breadth. The longer path is to be 3 m wide and the shorter is to be 2 m wide. The cost of grassing the remaining part of the park @ Rs. 1000 per ha is

Solution:

Area of the park minus the paths
= (200 - 3) (150 - 2)
= 197 × 147 sq. m
= 29156 sq. m
The cost of grashing the remaming part of the park = Rs 29156/10000 x 1000
= Rs 2915.6
