A. 3%
B. 4%

D. 6%
S.I. = Rs. (15500 – 12500) = Rs. 3000.
Rate = ( 100 X 3000/12500 X 4 )% = 6%.
A. 4 : 3
B. 3 : 2
C. 6 : 5
D. 7 : 6
E. None of these
Explanation:
Let x be the investment of Rayan in 6% and y be in 7%
x(6)(n)/100 = y(7)(n)/100
=> x/y = 7/6
x : y = 7 : 6
A. 3 1/3 km/hr
B. 3 1/9 km/hr
C. 1 ¼ km/hr
D. 4 2/3 km/hr
Explanation:
Let Speed upstream = x km/hr
Speed downstream = 3x km/hr
Speed in still water = ½ (x+3x) km/hr = 2x km/hr
Speed of current = ½ (3x-x) km/hr = x km/hr
2x = 28/3 or x = 14/3 = 4 2/3 km/hr
A. 31.00
B. 31.01
C. 32.00
D. 32.2
23 + 29 + 31 + 37 + 41 = 161/5 = 32.2
A. Remains same
B. 5% decrease
C. 5% increase
D. 10% increase
Explanation:
100 * 100 = 10000
125 * 80 = 10000
No change
A. Rs. 1505
B. Rs. 1510
C. Rs. 1500
D. Rs. 1490
E. None of these
Explanation:
Let the cost price of an article be Rs. x.
(19% of x) – (12% of x) = 105
19x/100 – 12x/100 = 105 => 7x = 105 * 100
=> x = 1500
Cost price = Rs. 1500
