Directions (Q. 1 – 5):

(36/100)*420 – (56/100)*350 = x – 112 – 3025

151.2 – 196 + 112 + 3025 = x

X = 3092.2

(53/3)*180 + (1/4)* 480 = x

3180 + 120 = x

X = 3300

(9801/121) * 6.5 = (x/6)

81 * 6.5 * 6 = x

X = 3159

56 × 12 – 48 × 896 ÷ 112 = x

672 – 384 = x

X = 288

(8/3) * (11/3) *(x/11) = (8/3) *(7/5)*(6/7)

(X/3) = (6/5)

X = 18/5 = 3.6

Directions (Q. 6 – 10):

The pattern is, *8, *4, *2, *1

The pattern is, *0.5 + 0.5, *1 + 1, *1.5 + 1.5, *2 + 2,..

The alternative difference is, 8, -8…

The pattern is, *6 + 5, *5 +4, *4 + 3, *3 + 2,..

The pattern is, +13 – 1, +23 – 2, +33 – 3, +43 – 4,..

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

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

Ratio of efficiency of a man to that of a woman= 3/5:1/3= 9:5

So, 36*x*9=48(x+7)*5

By solving, x=20 days

Total age of 30 students= 16*30= 480

Including teacher total weight= 31* 17= 527

Age of teacher = 527- 480 = 47

Age of teacher’s wife = 43

A= 60000*12= 720000

B= 40000*4 + 28000*8 = 384000

C= 30000*6= 180000

Ratio of investment= 60:32:15

Total profit= 4500/15*107 = Rs. 32100

Directions (Q. 16 – 20)

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

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

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 %

The total no of Dell laptops were 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 no of HP laptops were 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

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
