A. 33500
B. 23500
C. 22500
D. 24500
Explanation:
421 * 0.9 + 130 * 101 + 10000
= 378.9 + 1313 + 10000 = 23508.9 = 23500
A. 24000
B. 23000
C. 22000
D. 25000
25 * 2 * 0.75 = 20/100 * 10/100 * 7.5/100 * x
25 = 1/100 * x => x = 25000
A. 20
B. 30
C. 60
D. None of these
Explanation:
Area of the plot = (3×1200)Sq.m = 3600 Sq.m
Breadth = x meters and length = 4x meters
4x × x = 3600 or x2 = 900 0r x = 30
Length of plot = 4x = (4×30) m = 120 m
A. -5, 3
B. 3, 5
C. -3, 5
D. -3, -5
Explanation:
x2 + 5x – 3x – 15 = 0
x(x + 5) – 3(x + 5) = 0
(x – 3)(x + 5) = 0
=> x = 3 or x = -5.
A. 25%
B. 33 1/3 %
C. 50%
D. 66 2/3 %
Explanation:
Let C.P. of each pen be Re. 1.
Then, C.P. of 8 pens = Rs. 8; S.P. of 8 pens = Rs. 12.
Gain % = 4/8 * 100 = 50%
A. 16 toffees
B. 20 toffees
C. 25 toffees
D. 24 toffees
Explanation:
He sells 20 toffees
S.P = Rs. 1 and loss = 4%
C.P = (11/96 × 1) = Rs. 25/24
Gain = 20%
S.P = Rs. (120/100 × 25/24) = Rs. 5/4
Rs. 5/4 toffees sold = 20
Rs. 1 toffees sold = (20 × 4/5) = 16
A. Rs.7500
B. Rs.7200
C. Rs.6000
D. Rs.5750
Explanation:
x* 12 : 2x* 6: 3x* 4
1:1:1
1/3 * 18000 = 6000
