Let the CP of the article be 100,
S.P = 85
To gain profit of 2 percent S.P = 187
According to the question,
(102/17) * 100 = Rs. 600
13) Answer: a)
Let B get the amount = x
A = 2x/3
C = 5x
According to the question,
(2x/3) + x + 5x = 960
X = 144
Thus the amount of B = Rs. 144
14) Answer: d)
Cost of one banana = 5/4
Selling price of one banana = 8/5
Profit % = ((8/5 – 5/4) * 100)/ (5/4) = 28 %
15) Answer: d)
Let the income of the man is 1000
His expenditure =400
Thus his saving
= > 1000 – 400 = 600
His increased income= 1250
Expenditure= 464
New saving = 1250 – 464 = 786
Percentage increase in saving
= > (186/600) * 100 = 31 %
16) Answer: b)
Let the speed of train be x and y m/s
According to the question,
Difference between the speeds of the train
= > 280/70 = 4 m/s = (x – y)
Sum of the speed of both the train
= > 280/7 = 40 m/s = (x + y)
Thus
X = 22 m/s
Y = 18 m/s
17) Answer: b)
Let the speed of sudhir in still water is x km/h and speed of stream is y km/h
According to the question,
42/(x + 4) = 3——- (I)
42/(x – 4) = 7——- (II)
According to the question,
42/(x + 4) + 42/(x – 4) = 10
42x/(x2 – 16) = 5
42x = 5x2 – 80
5x2 – 42x – 80 = 0
By solving the equation, we get,
X = 10
Speed of still water = 10 km/hr
18) Answer: a)
Let the income of Sachin and Rahul is 11x and 6x respectively,
Income – Savings = Expenditure
According to the question,
(11x – 2000)/(6x – 2000) = 5/2
22x – 4000 = 30x – 10000
8x = 6000
X = 750
Thus, the income of Sachin and Rahul is Rs. 8250 and Rs. 4500
19) Answer: a)
