Directions (Q. 1-5)

52.6 ÷ [3/4 of (52+64) – 15 1/4] = x

52.6 ÷ [87- (61/4)] = x

52.6 ÷ [(324-61)/4] = x

X = 52.6 × 4 / 287

X = 0.7

[(25.3 × 33) ÷ 23 – 1560 ÷ 120] = 4x

36.3 -13 = 4x

4x = 23.3

X = 23.3/4

X = 5.825

3 5/18 × 5 ¼ × 11 3/7 + 2 2/5 = x

(59/18) × (21/4) × (80/7) + 12/5 = x

(590/3) + (12/5) = x

X = (2950+36)/105 = 2986/15

X = 199 1/15

(3333 ÷ 15) + (735 ÷ 35) + (4056 ÷ 26) = x

222.2 + 21 + 156 = x

X = 399.2

(45)2 ÷ ∛3375 + (35)2 ÷ 15 = x

[(45*45)/15] + [(35*35)/15] = x

X = 135 + (245/3)

X = (405+245)/3 = 650/3

X = 216 2/3

Directions (Q. 6-10):

The pattern is, *0.5 +0.5, *1 +1, *1.5+1.5, *2 +2, *2.5 +2.5,..

The pattern is, + (1*2), + (2*3), + (3*4), + (4*5), + (5*6),..

The difference of difference is, 5, 6, 7, 8

The pattern is, +212, -192, +172, -152, +132,..

The pattern is, 73 -7, 82-8, 93 -9, 102 -10, 113– 11,..

Compounded yearly,

= > 7500*(4/100) = 300

C.I = 300

Compounded half yearly,

= > 7500*(2/100) = 150

= > 7650*(2/100) = 153

C.I = 303

Difference = 303 -300 = 3

In an election between 2 parties, one got 40 % but lost it by 400 votes

One person got 40 %, 60 %

According to the question,

(60-40) % of the votes = 400

20 % of the votes = 400

Total votes = 400*(100/20) = 2000

Let the total investment be x,

The ratio of profit of A, B and C,

= > [(1/4)x * (3/4)*12] : [(2/5)x * (1/4)*12] : [(7/20)x * 3]

= > (9/4)x : (6/5)x : (21/20)x

= > (9/4) : (6/5) : (21/20)

= > 45 : 24 : 21 à 15: 8: 7

Total profit = Rs. 18000

30’s = 18000

1’s = 600

The share of B = 8’s = 600*8 = 4800

Sum of the ages of mother and son = 50 years

After 5 years, mother: son = 9 : 3(9x, 3x)

According to the question,

9x-5 + 3x -5 = 50

12x = 60

X = 5

The present age of mother and son = 9x-5, 3x -5

= > 40, 10

5 years ago, the ratio of age of mother and son = 35 : 5 = 7 : 1

2. P1 = 52000, Loss = 7 %

S.P1 = 52000 * (93/100)= 48360

With that money she purchased another tv set and sold it at the profit of 5 %,

C.P2 = 48360

S.P2 = 48360*(105/100) = 50778

The overall loss = 52000 – 50778 = Rs. 1222

Directions (Q. 16 – 20):

Sale of A = 84000 x 65/100 = 54600

Sale of B = 56000 x 70/100 = 39200

Therefore total sale = 54600 + 39200 = 93800

B in 2011 = 78000 x 60/100 = 780 x 60

A in 2013 = 68000 x 60/100 = 680 x 60

Therefore Ratio = 780 x 60 : 680 x 60 = 39 : 34

Sale of A = 70000 x 52/100 = 36400

Total number of motorcycles produced by B = 81000

Therefore required % = 36400/81000 x 100 = 44.938 = 45% (approx.)

Total no. of motorcycles sold by B

= 56000 x 70/100 + 78000 x 60/100 + 80000 x 55/100 + 60000 x 70/100 + 81000 x 63/100 = 39200 + 46800 + 44000 + 42000 + 51030 = 223030

Therefore Average = 223030/5 = 44606

A in 2011 = 72000 x 58/100 = 41760

A in 2012 = 92000 x 75/100 = 69000

Therefore Required % rise = (69000 – 41760)/41760 x 100 = 27240 x 100/41760 = 65.229 = 65% (approx.)
