The difference is, [(3*5)-1], [(3*6)-1], [(3*7)-1], [(3*8)-1],..

The answer is, 282

The pattern is, +02, -32, +62, -92, +122

The answer is, 219

The pattern is, *1 + 22, *2 + 32, *3 + 42, *4 + 52,..

The answer is, 2237

The pattern is, 4*5*6, 5*6*7, 6*7*8, *7*8*9, 8*9*10, 9*10*11,..

The answer is, 990

The pattern is, +212, +232, +252, +272,..

The answer is, 2675

Directions (Q. 6 – 10):

[(17.5*7) – (1320/120)] = 4x

4x = 122.5 โ 11

X = 111.5/4 = 27. 875

[((48*48)/24) * x] รท 11 = 576

96x/11= 576

X = (576*11)/96 = 66

(32*32)/8 + 225/ 25 = x

X = 128 + 9 = 137

(1/2)* 8436 + (98/100)*528 + 253 = x

X = 4218 + 517.44 + 253

X = 4988.44

(1344 รท 14) รท 4 + โ3136 + x = 802

(96/4) + 56 + x = 802

24 + 56 + x = 802

X = 802 โ 80

X = 722

Total Balls = 15

Required Probability = 6C3 / 15C3 = 4/91

Remainder amount after deducting their share = 3530- (5+10+15) = Rs 3500

Bโs share = [3500*5/14] + 10= Rs. 1250 + 10 = Rs. 1260

Initial investment of A, B, and C= 3x: 4x: 5x

Ratio of profit

= [3x*4 +(3x- 9x/12)* 8] : [4x*12] : [5x*12]

= [12x + 18x] : [48x] : [60x]

= 30x : 48x : 60x

= 5x : 8x : 10x

23x = 9200

x= 400

Share of B = 8*400= Rs. 3200

C can empty the tank in =18/60*100= 30 hours

Total units of work= 360

Aโs one hour work= 360/18= 20 units

Bโs one hour work= 360/24= 15 units

Cโs capacity to empty in one hour= 360/30= 12 units

When three pipes are opened simultaneously then in one hour they will

(20+15-12)=23 units

In 12 hours they will fill= 23*12= 276 units

After 12hrs, C will be closed

Time taken by A& B to fill the remaining tank= 84/35= 2 2/5 hours

Total time will be= 12 + 2 2/5 = 14 2/5 hours

Selling price = 1320*70/100= 924

Cost price = (924/110)*100= Rs. 840

Directions (Q. 16 – 20):

Number of shares sold in Chennai by Company A= (4200ร62)/100=2604

Similarly, by Company B= (68ร4200)/100=2856

By Company D= (36ร4200)/100=1512

By Company E= (4200ร54)/100=2268

Required ratio= (2604+2856)/(1512+2268) = (5460/3780)

=546/378=13/9=13:9

Required difference

= [8600 ร (40+25+45)]/100- [4000ร (28+53+55)]/100

= 9460-5440 =4020

Required % less= [(50ร49-48ร30) / (50ร49)] ร100

= [(2450-1440)/2450] ร 100

= [1010/2450]ร100 = 41.22%

Required average=1/6ร 4800[(60+30+40+50+57)/100]

= (800ร282)/100 = 2256

Required answer = [4000* (27/100) + 5000*(32/100) + 4200*(58/100) + 8600*(45/100) + 4800*(57/100)]

= [1080 + 1600 + 2436 + 3870 + 2736]

= 11722
