1.e)

Let the number of students be x

No.of Students above 8 years of age = (100-20)% of x=80%of x

80% of x= 48+2/3 of 48

8x/10=48+32

8x/10=80

x=100

2.a)

Initial Population = 1,60,000

In first year, 4% increased In 2nd year , 5% increased

After 2 years the total population In 3rd year, 8% increased

After 3 years the total population 3.b) 4.c)

A=XY/100

B=XY/100

5.c)

manufacturing cost = Rs 60

Raw materials cost = Rs 40

Original Profit 1/4 of Manufacturing Cost = 15 rs

So original selling is price 60 + 40 + 15=  Rs 115

New raw material cost = 40 + 30 = 70

New manufacturing cost = 60 + 20 = 80

New cost of the product = 150

New selling price = 115 + 60 = 175

New profit percentage = (27/175)*100=16.666=16.7

6.e)

Let the price of 1 litre of petrol be Rs.x and let Raj initially buys ‘y’ litres of petrol.

Therefore, he would have spent Rs. xy on petrol.

When the price of petrol increases by 25%, the new price per litre of petrol is 1.25x.

Raj intends to increase the amount he spends on petrol by 15%.

i.e., he is willing to spend xy + 15% of xy = 1.15xy

Let the new quantity of petrol that he can get be ‘q’.

Then, 1.25x *q = 1.15xy

As the new quantity that he can buy is 0.92y, he gets 0.08y lesser than what he used to get earlier.

Or a reduction of 8%.

7.c)

B/A= ( A/(A/B))

B/A=X

X=  1/(1+(B/A))

X=1/(1+X)

solving we get x=0.62

x=62%

8.a)

Let the number of candidates appearing from each state be X.

Then,

7% of X – 6% of X = 80

Or, 1% of X = 80

Or, X = 8*100

X = 8000.

9.b) First Part =(1.8/2)*20000

=0.9*20000=18000

Second Part = 20000-18000

Second Part = 2000

Second Part = 20000-18000

Second Part =2000

10.b)

8000-4000=4000

20% of 4000 =(4000/20) * 20

= 20,000
