QUESTION: 2

Ram is 30 yrs younger than his uncle today. Five yrs ago, Ram was 1 4 th as old as his uncle.How old will Ram's uncle be 5 yrs from today?

Solution: Let at present the ages of uncle and Ram are x and y years respectively. Then
x - y = 30 .....(1)
y - 5 = 1 4 (x - 5)
⇒ 4y - 20 = x - 5
⇒ x - 4y = -15 .....(2)
On solving, we get
y = 15 and x = 45
∴ Age of uncle after 5 years
= 45 + 5 = 50 years

QUESTION: 8

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

Chord AB of a circle radius 28 cm subtends an angle of 90º at the centre of the cirlce. The area of the major segment is .... (use π = 3.14)

Solution:

Radius of circle r = 28 cm
π = 3.14
θ = 90º
where θ is the angle subtended at the centre of the circle

= 615.44 - 392
= 223.44
Area of circle = πr2 = 3.14 x 28 x 28 = 2461.76
Area of major segment = Area of circle - Area of minor segment
= 2461.76 - 223.44 = 2238.32 cm2

QUESTION: 40

A solid cube of side 20 cm is cut into 8 equal cubes. The total surface area increases by

Solution:

Edge of the cube = 20 cm
Volume of the cube = (Edge)3 cm3
= (20)3 cm3
= 8000 cm3
Number of smaller cube = 8
Volume of the 1 smaller cube = 8000/8 cm3 = 1000cm 3
Side of the smaller cube = a
∴ a3 = 1000
⇒ a = 10 cm
Surface area of the cube = 6(side)2
Surface area of solid cube whose side is 20 cm = 6 x (20)2 = 2400 cm2
Surface area of cube whose side is 10 cm = 6 x (10)2 = 600 cm2
Surface area of 8 small cube = 8 x 600 cm2 = 4800 cm2
∴ Total surface area increase
