A. 600
B. 700
C. 800
D. 900
Explanation:
(40/100) * X – (20/100) * 650 = 190
2/5 X = 320
X = 800
A. Rs.5000
B. Rs.25000
C. Rs.7500
D. Rs.8500
Explanation:
Income = Rs. 100
Expenditure = Rs. 80
Savings = Rs. 20
Present Expenditure 80*(20/100) = Rs. 96
Present Savings = 100 – 96 =Rs. 4
100 —— 4
? ——— 200 => 5000
A. 35, 25 kmph
B. 80, 40 kmph
C. 40, 60 kmph
D. 50, 55 kmph
Explanation:
Speed downstream = 60 + 20 = 80 kmph
Speed upstream = 60 – 20 = 40 kmph
A. 1.8 km/hr
B. 3 km/hr
C. 3.6 km/hr
D. 4 km/hr
Let x be the speed of the river.
Ds = (6 + x) km/hr; Us = (6 – x) km/hr
If t hours is the time to row downstream then 4t hours is the time to row upstream.
(6 + x)*t = (6 – x)*4t
6 + x = 24 – 4x
x = 3.6 km/hr
A. Rs.3600
B. Rs.4000
C. Rs.4500
D. Rs.3000
Explanation:
X * (90/100) * (80/100) * (75/100) = 1944
X * 0.9 * 0.8 * 0.75
X = 1944/0.54
X = 3600
A. Rs. 350
B. Rs. 390
C. Rs. 252
D. Rs. 316
Explanation:
Savings % = (100 – 65) % = 35 %
Saving = 35 % of Rs. 720
= Rs(35/100 ×720) = Rs. 252
A. Rs.2250
B. Rs.2000
C. Rs.2150
D. Rs.2200
