Directions (Q. 1-5):

(8/5) × 404 + (98/100) × 820 + (5/4) ÷ (9/63) =x

X= 646.4 + 803.6 + 8.75

X= 1458.75

0.8% of 3072 + 12% of 785 =x

X= (8/1000) × 3072 + (12/100) × 785

X= 24.576 + 94.2

X= 118.776

2162 ÷ 46 × 23 + 287 -189 =x

X= 1081 +287 -189

X= 1179

x % of (400 + 16 ÷ 0.2 ÷ 0.05) =1700

(x/100) × (400 + ((160/2) × (100/5)) =1700

(x/100) × (400 + 1600) =1700

(x/100) × 2000 = 1700

20x = 1700

X= 85

8195/745 + x/12 =7847

11 + x/12 =7847

x/12 = 7836

x= 94032

Directions (Q. 6-10):

The pattern is, ÷ 6, ÷ 5, ÷ 4, ÷ 3, ÷ 2

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

The pattern is, +(13*1), +(13*2), +(13*4), +(13*8), +(13*16)

The pattern is, *1+12, *2+22, *3+32, *4+42, *5+52

The pattern is, *8 – 7, *7 -6, *6 -5, *5 -4,..

The average monthly income of a family of 6 members was 21600,

Total monthly income of a family of 6 members= 21600*6= 129600

One of the daughters got married and left the home, now the average = 18200

Total monthly income of a family of 5 members = 18200*5 = 91000

Monthly income of married daughter= 129600 – 91000 = 38600

5 years ago, the ratio of ages of Abi and Pari = 5:3 (let us assume the age of abi and pari = 5x, 3x)

Neela = Abi – 5

Neela = Pari + 5

Abi – 5 = Pari + 5

(5x + 5) – 5 = (3x + 5) + 5

2x= 10=> x= 5

Abi= 25+5 = 30, Pari= 15+5 =20

Neela’s Present age= Abi – 5= 25 years

The difference between the S.I and C.I for 2 years,

Diff= sum*(r/100)2

105 = sum*(5/100)2

Sum= 42000

Both the trains are running at the same direction,

So, relative speed= S1 – S2

Distance= Train length1+ Train length2

The first train takes to cross the second one in,

T = D/S

T= (155+175)/((81 – 45)*(5/18))

T= 330/(36*(5/18))

T= 330/10 = 33 sec

The speed of upstream= D/T = 9.6/(24/60) = 24 km/hr

The speed of the current =  ¼ of the boat in still water

Speed of boat : Speed of Current = 4:1 = (x: 4x)

Speed of Upstream = Speed of boat – Speed of Current = 3x

24 = 3x

X= 8

Speed of boat = 32 km/hr, Speed of Current = 8 km/hr

Speed of downstream= Speed of boat + Speed of Current = 5x

Speed of downstream = 40 km/hr

Time = 36 min= (36/60) hr

Distance= S*T = 40*(36/60) = 24 km

Directions (Q. 16 – 20):

For factory F = 25*5/100*1/5 and for factory D = 25*(8/100)*(5/8)

% percent = [25*5/100*1/5]/ [25*8/100*5/8] = 1/5*100 = 20%

For product X cost of production = 25*12/100*1/3 = 1 crore and for product Y it is 2 crore.

Now profit earned on X = 1*130/100 – 1 = 0.3 crore and profit earned on Y = 2*124/100- 2 = 0.48 crore.

Total profit = 0.3 + 0.48 = 0.78 crore or 78 lakh

Ratio = 25*15/100*2/5 : 25*8/100*3/8 = 2:1

(8/100)*25*(5/8) = 1.25 crore

1.25*(125/100) = 1.56 crore, profit = 1.56 – 1.25 = 31 lakh
