A. 1.4
B. 1.6
C. 1.5
D. 1.2
Explanation:
(180/37 of 14.8) / (17/60.1 of 180.30) = 72/51 = 24/17 = 1.41
A. 120 sq m
B. 300 sq m
C. 150 sq m
D. 480 sq m
1/2 * 15 * 20 = 150
A. 18
B. 15
C. 12
D. 5
2x/25 = 6/(x/3) 2x/25 = 18/x 2x*x = 18*25 x² = 9*25 x=3*5 x=15
A. Rs.240
B. Rs.350
C. Rs.340
D. Rs.390
Explanation:
(3*8 + 2*4):(4*8 + 5*4)
8:13
8/21 * 630 = 240
A. 16 2/3%
B. 6 2/3%
C. 8%
D. 15%
A. 42.75%
B. 31.25%
C. 35.5%
D. 40.5%
E. None of these
Explanation:
Let the required percentage be x%.
3/20 = x% of 12/25 => 3/20 = x/100 * 12/25
=> 12x = (300 * 25)/20 => x = (25 * 25)/20
=> x = 31.25%.
A. 8/15, 9/13, 6/11
B. 8/15, 6/11, 9/13
C. 9/13, 6/11, 8/15
D. 6/11, 8/15, 9/13
Explanation:
The fractions considered are 8/15 9/13 6/11
To compare them we make the denominators the same. So the fractions are
(8 * 13 * 11)/2145, (9 * 15 * 11)/2145 and (6 * 15 * 13)/2145
1144/2145, 1485/2145 and 1170/2145
so in descending order the fractions will be
1485/2145, 1170/2145 and 1144/2145 i.e., 9/13 , 6/11 , 8/15
