Answers :
1) Answer: b)
The difference between the simple interest and compound interest for 3 years is,
Difference = [Sum* r2 * (r + 300)]/1003
2835 = [Sum*225*315]/1003
Sum = (2835*100*100*100)/(225*315)
Sum = Rs. 40000
2) Answer: a)
A’s one day work = (1/16)
B’s one day work = (1/12)
C’s one day work = (1/20)
(A + B)’s one day work = (1/16) + (1/12) = 28/(16*12) = 7/48
(A + B)’s 4 day work = (7/48)*4 = 7/12
Remaining work = 1 – (7/12) = 5/12
C can finish the remaining work in,
= > (5/12)*20 = 25/3 = 8 (1/3) days
(Or)
LCM of 16, 12 and 20 = 240
Total work = 240 units
A = 240/16 = 15 units per day
B = 240/12 = 20 units per day
C = 240/20 = 12 units per day
(A+B)’s 4 days work = (15+20)*4
= 35*4 = 140 units
Remaining = 240 – 140 = 100 units
Required number of day = 100/12 = 25/3 = 8 (1/3) days
3) Answer: b)
The ratio of share of A, B and C,
= [35000*4 + 35000*(3/5)*8]: [45000*4 + 60000*8]: [60000*7 + 60000*(2/5)*5]
= > 308000: 660000: 540000
= > 77: 165: 135
165’s = 49500
1’s = 300
Total profit = 377’s = 377*300
= > 113100
4) Answer: a)
Let the cost price be Rs. X,
X*(85/100) + 56 = x*(120/100)
(120x/100) – (85x/100) = 56
35x/100 = 56
X = 56*100/35
X = 160
Cost price = Rs. 160
Selling price = 160*(130/100) = Rs. 208
5) Answer: c)
The ratio of B’s age six years hence to C’s present age is 3 : 2 (3x, 2x)
Present ages of B to C = 3x – 6, 2x
Present ages of A to C = 2: 1 (2x, x)
Present ages of A, B and C = 4x, 3x – 6, 2x
B = A – 15
A – B = 15
4x – (3x – 6) = 15
4x – 3x + 6 = 15
X = 9
B’s age 4 years ago = 3x – 6 – 4 = 27 – 10 = 17 years
Direction (6-10) :
6) Answer: c)
In 2018, the price of Wipro laptop is,
= > 18000*(115/100) = 20700
In 2018, the price of Acer laptop is,
= > 23000*(120/100) = 27600
Total prices of Acer laptop from the year 2012 to 2018,
= > 15000 + 17000 + 24000 + 32000 + 25000 + 23000 + 27600
= > 163600
Total prices of Wipro laptop from the year 2012 to 2018,
= > 22000 + 27000 + 33000 + 19000 + 36000 + 18000 + 20700
= > 175700
Required sum = 163600 + 175700 = 339300
7) Answer: b)
Total Cost price
= > 15*25000 + 28*29000 + 12*30000 + 35*28000 + 18*36000
= > 375000 + 812000 + 360000 + 980000 + 648000
= > 3175000
Total laptops sold = 108
Total selling price = 108*25000 = 2700000
Loss in the year 2016,
= > 3175000 – 2700000
= > 475000
8) Answer: c)
The average prices of different types of laptops in 2013,
= > [(17 + 22 + 25 + 30 + 27)*1000]/5
= > 121000/5 = 24200
The average prices of different types of laptops in 2015,
= > [(32 + 26 + 29 + 35 + 19)*1000]/5
= > 141000/5 = 28200
Less % = (4000/28200)*100 = 14.18 % = 14 %
9) Answer: a)
The total number of Dell laptops was sold in the year 2014 = 20000
Prices of Dell laptops in the year 2014 = 19000
Total Income for Dell = 20000*19000 = 38 Crore
The total number of HP laptops was sold in the year 2014 = 18000
Prices of HP laptops in the year 2014 = 29000
Total Income for HP = 18000*29000 = 52.2 Crore
Required difference = (52.2 – 38) crore = 14.2 Crore
10) Answer: b)
In 2012, Total prices of all laptops = (15 + 24 + 18 + 28 + 22)*1000 = 107000
In 2013, Total prices of all laptops = (17 + 22 + 25 + 30 + 27)*1000 = 121000
In 2014, Total prices of all laptops = (24 + 19 + 27 + 29 + 33)*1000 = 132000
In 2015, Total prices of all laptops = (32 + 26 + 29 + 35 + 19)*1000 = 141000
In 2016, Total prices of all laptops = (25 + 29 + 30 + 28 + 36)*1000 = 148000
In 2017, Total prices of all laptops = (23 + 27 + 29 + 32 + 18)*1000 = 129000
