A and B rent a pasture for 10 months. A put in 80 cows for 7 months. How many can B put in for the remaining 3 months, if he pays half as much again as A?
A. 120
B. 180
C. 200
D. 280
Explanation:
80* 7: x* 3 = 1:1 1/2
560: 3x = 2: 3
x = 280
A. 120
B. 180
C. 200
D. 280
Explanation:
80* 7: x* 3 = 1:1 1/2
560: 3x = 2: 3
x = 280
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
A. Rs.2400
B. Rs.3600
C. Rs.2850
D. Rs.2000
Explanation:
First persons investment = x
Second persons investment = x + 1000
Third persons investments = x + 2000
x + x + 1000 + x + 2000 = 9000
3x = 6000
x = 2000
Ratio = 2000 : 3000 : 4000
2:3:4
4/9 * 54000 = 2400
A. Rs.2450
B. Rs.3600
C. Rs.2500
D. Rs.3100
Explanation:
A:B:C = 2/3:1/6:1/6 = 4:1:1
x * 2/100 * 2/3 = 200
B capital = 15000*1/6 = 2500
A. 1/3 rd
B. 2/5 th
C. 2/3 rd
D. 1/5 th
Explanation:
3h = 5c
6c = 10s
A = 21h*3 + 15c*2
= 63h + 30c
= 105c + 30c = 135c
B = 15c*6 + 40s*7 1/2
= 90c + 300s
= 90c + 180c = 270c
A:B = 135:270
27:52
A = 27/79 = 1/3
A. Rs.270
B. Rs.185
C. Rs.215
D. Rs.380
Explanation:
12*8 :16*9 = 18*6
8: 12: 9
9/29 * 870 = 270
A. 4 months
B. 6 months
C. 7 months
D. 9 months
Explanation:
45*12 : 54*x = 2: 1
x = 5
12 -5 = 7
A. 1750
B. 1900
C. 8600
D. 10300
Explanation:
65 * 6 : 84 * 5 : 100 * 3
26:28:20
C = 74000 * 95/100 = 7030 * 20/74 => 1900
A. Rs.4500
B. Rs.5200
C. Rs.1800
D. Rs.3000
Explanation:
A:B:C = 5:6:4
Let the total profit = 100 – 30 = 70
5/15 * 70 = 70/3
A = 70/3 + 30 = 160/3
B + C = 100 – 160/3 = 140/3
A-(B+C) = 160/3 – 140/3 = 20/3
20/3 —- 200
100 —- ? => 3000
A. 3:4:5
B. 12:15:20
C. 20:15:12
D. 6:8:10
Explanation:
6A = 8B = 10 C
A:B:C = 1/6:1/8:1/10
= 20:15:12
