1).
Least
Cost Price = Rs. (200 * 8) = Rs. 1600.
Greatest
Selling Price = Rs. (425 * 8) = Rs. 3400.
Required
profit = Rs. (3400 - 1600) = Rs. 1800.
Answer: c)
2).
Let
C.P. be X
1920-x/x*100
= x-1280/x*100
1920-x
= x-1280
2x=
3200, x= 1600
s.p.
= 125%of 1600= 125/100*1600 = 2000
Answer: a)
3).
Let's
take the present age of the elder person = x
and
the present age of the younger person = x – 16
(x
– 6) = 3 (x-16-6)
=>
x – 6 = 3x – 66
=>
2x = 60
=>
x = 60/2 = 30
Answer: c)
4).
Train crosses the man in 20 sec.
So
length of train / speed of train in m/sec = 20 sec
L/(54*5/18)=
20 ; Length of train= 300 m
Now
length of train+ platform/ (54*5/18)= 36 sec
On
solving Length of Platform = 240 m
Answer: c)
5).
Radius
of the circle (r) = 28 cm.
Length
of the wire (circumference) = 2 pi r = 2 pi 28 = 176 cm
Let
side of the square be "a" cm.
Perimeter
of square(4a) = Circumference of the circle = 176 cm
or,
4a = 176 cm
or,
a = 44 cm
Thus, side of the square is 44 cm.
Answer: a)
6).
Let
C = x.
Then,
B = x + 5000 and A = x + 5000 + 4000 = x + 9000.
So,
x + x + 5000 + x + 9000 = 50000
=> 3x = 36000
=>
x = 12000
A
: B : C = 21000 : 17000 : 12000 = 21 : 17 : 12.
A's share = Rs.(35000 x 21/50) = Rs. 14,700.
Answer: d)
7).
This
problem is similar to the problems we saw in compound interest.
We
can use the formulas of compound interest here as well.
Rate
of increase = 1/5×100=20%
Height
after 2 years = P(1+R/100) T
=
50(1+20/100)2=50(1+1/5)2
=50(6/5)2=(50×6×6)/(5×5)=2×6×6=72
cm
Answer: b)
8).
Let
l = 9 ft.
Then
l + 2b = 37
2b
= 37 - l = 37 - 9 = 28
b
= 28/2 = 14 ft.
Area
= lb = 9 × 14 = 126 sq. ft.
Answer: a)
9).
Let
breadth = x cm
Then
length = 2x cm
Area
= lb = x × 2x = 2x2
New
length = (2x - 5)
New
breadth = (x + 5)
New
Area = lb = (2x - 5)(x + 5)
But
given that new area = initial area + 75 sq.cm.
(2x - 5)(x + 5) = 2x^2 + 75
2x^2 + 10x - 5x - 25 = 2x^2 + 75
5x - 25 = 75
5x = 75 + 25 = 100
x = 100/5 = 20 cm
Length
= 2x = 2 × 20 = 40cm
Answer: c)
10).
Suppose
A invested Rs.11 for 8 months and B invested Rs.12 for y months.
Then
ratio of investment of A and B = (11x8) : (12xy)
=
88 : 12y
88/12y
= 2/3
24y
= 88x3
y
= 264/24 =11 months.
