Answers :
1) Answer: b)
Let the cost price be x,
According to question
104x – 94x = 160
10x = 160
Cost Price of the article = (160/10)*100 = Rs. 1600
Profit = 1760 – 1600 = Rs. 160
Profit % = (160/1600)*100 = 10 %
2) Answer: d)
According to the question,
(X/12) + (10/15) = 1
X/12 = 1 – (2/3)
X/12 = 1/3
X = 4 days
3) Answer: a)
The ratio of present age of A and B = 5: 7 (5x, 7x)
After 5 years, the ratio will be = 3: 4
(5x + 5) / (7x + 5) = ¾
20x + 20 = 21x + 15
X = 5
Present ages of A and B is 25 years and 35 years respectively
Required difference = 35 – 25 = 10 years
4) Answer: c)
The difference between CI and SI for three years is,
Diff = Sum*[r2 * (300 + r)]/1003
1240 = Sum*[102 * 310]/1003
1240 = Sum*[100*310]/[100*100*100]
Sum = (1240*100*100*100)/(100*310) = Rs. 40000
5) Answer: b)
The share of A, B and C,
= > [4x*1 + 4x*(50/100)*1] : [5x*1 + 5x*(130/100)*1] : [6x*2]
= > [4x + 2x] : [5x + (13x/2)] : [12x]
= > 6x : 23x/2 : 12x
= > 12 : 23 : 24
Total profit = Rs. 118000
The share of B = 118000*(23/59) = Rs. 46000
6) Answer: d)
Total number of T2 cars sold in city P, Q and S together
= > 132000*(22/100)*(2/5) + 132000*(18/100)*(1/2) + 132000*(24/100)*(4/11)
= > 11616 + 11880 + 11520 = 35016
Required average = 35016/3 = 11672
7) Answer: c)
Total number of T1 cars sold in City P
= > 132000*(22/100)*(3/5) = 17424
The total number of T2 cars sold in City T
= > 132000*(21/100)*(5/12) = 11550
Required % = [(17424 – 11550)/11550]*100 = 50.857 % = 51 % more
8) Answer: b)
In city P, T2 cars = 132000*(22/100)*(2/5) = 11616
In city Q, T2 cars = 132000*(18/100)*(1/2) = 11880
In city R, T2 cars = 132000*(15/100)*(5/9) = 11000
In city S, T2 cars = 132000*(24/100)*(4/11) = 11520
In city T, T2 cars = 132000*(21/100)*(5/12) = 11550
So, City Q sold highest number of T2 cars.
9) Answer: b)
The total number of T1 cars sold in City Q and S together
= > 132000*(18/100)*(1/2) + 132000*(24/100)*(7/11)
= > 11880 + 20160 = 32040
The total number of T1 cars sold in City R and T together
= > 132000*(15/100)*(4/9) + 132000*(21/100)*(7/12)
= > 8800 + 16170 = 24970
Required difference = 32040 – 24970 = 7070
10) Answer: c)
The total number of cars sold in City P, R and T together
= > (22 + 15 + 21)/100 = 58/100
The total number of cars sold in City Q, R and S together
= > (18 + 15 + 24)/100 = 57/100
Required ratio = 58/100: 57/100 = 58: 57
