Directions (Q. 1 – 5):

The pattern is, *1 + 22, *2+32, *3+ 42, *4 + 52, *5 + 62,..

The difference of difference is, 41, 42, 43, 44,..

The pattern is, *4 -1, *4 -3, *4 -5, *4 โ 7,..

The pattern is, *1 + 25, *3 + 75, *5 + 125, *7 + 175, *9 + 225,..

The pattern is, + (113 + 11), + (103+ 10), + (93 + 9), + (83 + 8), + (73 + 7),..

Directions (Q. 6 – 10):

ย (16/100)*800 – (4/7)*x = 15

128 -15 = (4x/7)

113 = (4x/7)

(113*7)/4 = x

X = 196 = 200

ย (15/8)*(160/260) ร 520 = x โ 27

600 + 27 = x

X = 627 = 630

ย (7/11)*20350 โ (18/100)*1400 = x

12950 โ 252 = x

X = 12698 = 12700

X + 125 โ (258*14)/3 = 18

X + 125 โ 1204 = 18

X = 18 โ 125 + 1204

X = 1097 = 1100

ย (26)2 รท 13 = x โ (17/100)*2500

(26*26)/13 = x โ 425

52 + 425 = x

X = 477 = 480

The share of P, Q and R,

= > [6x*4 + 6x*(125/100)*8]: [4x*12]: [5x*4 + 5x*(3/4)*8]

= > 84: 48: 50

48โs= 24000

1โs = 500

Total profit = 182โs = Rs. 91000

If the interest compounded annually,

32000*(5/100) = 1600

33600*(5/100) = 1680

C.I = 1600 + 1680 = 3280

If the interest compounded half yearly,

32000*(5/200) = 800

32800*(5/200) = 820

33620*(5/200) = 840.5

34460.5*(5/200) = 861.5125

C.I = 800 + 820 + 840.5 + 861.5125 = Rs. 3322.0125

Required difference = 3322 โ 3280 = Rs. 42

The ratio of present age of A and Bโs age 6 years ago = 2: 1

The present age of A and B = 2x, x + 6

C = B + 8

C = A โ 7

B + 8 = A โ 7

X + 6 + 8 = 2x โ 7

X + 14 = 2x โ 7

X = 21

Present age of B = x + 6 = 27 years

ย (P + Q + R)โs one day work = (1/9) + (1/12) + (1/15)

= > (20 + 15 + 12)/180

= > 47/180

(P + Q + R)โs 3 day work = (47/180)*3 = 47/60

Remaining work = 1-(47/60) = 13/60

(Q + R)โs one day work = (1/12) + (1/15) = (15 + 12)/(12*15) = 9/60

Q and R can complete the work in 60/9 days

The remaining work will be completed by Q and R in,

= > (13/60)*(60/9) = 13/9 = 1 4/9 days

Area of equilateral triangle = (โ3/4)*a2

= > (โ3/4)*8*8

= > 16โ3 Sq m

Directions (Q. 16 โ 20)

Total Quantity of Wheat sold by the shop A and C together

= > 5.5 + 3 = 8.5 quintal

Total quantity of Wheat sold by the shop B and D together

= > 8 + 4 = 12 quintal

Required % = (8.5/12)*100 = 70 %

The total amount earned by shop B

= > (800*17) = 13600

The total amount earned by shop E

= > (600*16) = 9600

Required ratio = 13600: 9600 = 17: 12

The total amount earned by shop D, E and F together

= > [(400*19) + (600*16) + (450*18)]

= > [7600 + 9600 + 8100]

= > 25300

The total amount earned by shop B

= > 800*17 = 13600

The total amount earned by shop C

= > 300*21 = 6300

Required % = (13600/6300)*100 = 216 %

The total quantity of wheat sold by the shop A, B and E together

= > 5.5 + 8 + 6 = 19.5 quintal

The total quantity of wheat sold by the shop C, D and F together

= > 3 + 4 + 4.5 = 11.5 quintal

Required difference = 19.5 โ 11.5 = 8 quintal
