A. 120 cm2
B. 148 cm2
C. 74 cm2
D. 15 cm2
2(4*5 + 5*6 + 4*6) = 148
A. 20:23
B. 34:43
C. 32:45
D. 37:45
Explanation:
A : B
(8000*4)+(4000*8) : (9000*6)+(6000*6)
64000 : 90000
32 : 45
A. 70%
B. 90%
C. 80%
D. 75%
Explanation:
A B C D
90 100 80 100
A D
90 —– 100
360 —— ? = 400
500 —— 400
100 ——- ? => 80%
A. 140
B. 120
C. 160
D. 180
Explanation:
20% of 40 + ? % of 80 = 120
=> 800/100 + ?/100 * 80 = 120
=> ? = 140
A. 8.1375 * 104
B. 2.4123 * 104
C. 5.124 * 104
D. 6.125 * 104
Explanation:
? = 118500 – 33/4 * 4500 = 8.1375 * 104
A. 4 years
B. 6 years
C. 2 years
D. 3 years
Explanation:
9261 = 8000(21/20)N
(21/20)3 = (21/20)N => N = 3
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
