Answers:
1) Answer: A
Let the Maximum marks be x,
Passing mark is equal for both the students. So,
= > (40/100)x + 5 = (50/100)x -10
= > (10/100)x = 15
= > x = 150
Maximum mark = 150
Passing marks = 150*(40/100) + 5 = 60 + 5 = 65
2) Answer: B
Total number of valid votes =(75/100)*884000 = 663000
Percentage of votes polled in favour of Raghu = 84%
Therefore, the number of valid votes polled in favour of Raghu= 84% of 663000
= 84/100 × 663000
= 556920
3) Answer: C
Yuva gave 25% of a certain amount of money to Ram
Ram=25% of Yuva
From the money Ram received, he spent 20% on buying books and 35% on buying a watch
Remaining=100-(20%+35%)= 45%
45% of amount= 2700
=>(45/100)* X=2700
=> X=6000
Ram’s Total amount=6000
Ram=25% of Yuva
6000=(25/100)*Yuva
=>Yuva = 24000
4) Answer: A
Worth of the product after 2 years
= > 264000 * (80/100) * (80/100)
= > 168960
Worth of the product 2 years ago
= > x*(80/100) * (80/100) = 264000
= > x = 264000*(100/80)*(100/80)
= > x = 412500
5) Answer: B
Percentage of candidates failed is,
=50+40 – 10
=80
Percentage failed in current affairs or aptitude or both = 80%
Hence percentage passed = (100 – 80) %
=20%
6) Answer: C
The maximum marks for each subject is 250
Moni’s Maths mark=83
Science Mark = 66% = (66/100)*250=165
The overall percentage of all three subjects together
=> 64%= (64/100)* 750= 480
Moni’s mark,
Maths + Science + English=480
=>83+165+English=480
=>English=480-248
=>English=232
7) Answer: A
Let thr price of a phone be Rs.x
Then price of a camera = x+2000
S0 3(x+2000)+3x = 24000
3x+6000+3x=24000
6x+6000 = 24000
6x = 24000 – 6000
X = 18000/6
X = 3000
Therefore cost of a phone = Rs.3000
Cost of a camera = Rs. (3000+2000)=Rs.5000
Required percentage = (5000 – 3000/5000*100) %
= (2000/5000)*100%
= 40 %
8) Answer: A
10P/100 = 30Q/100 ——1
20Q/100 = 40R/100 ——-2
From 1, P =3Q
From 2, Q = 2R (Here, R =4000)
Q = 2*4000 = 8000
P=3Q =3*8000 = 24000
Hence P+Q+R = 24000+8000+4000
=36000
Therefore the total income is Rs.36000
9) Answer: B
Let Maximum marks be x,
Then (20% of x) + 10 = (30% of x) – 25
(20/100*x)+10 = (30/100*x) – 25
(20x/100)+10 = 30x /100 – 25
10x/100 = 35
X = 350
So passing marks = (20% of 350)+10
= (20/100*350) + 10
=80
42 % of maximum marks
= > (350)*(42/100)
= > 147
10) Answer: A
Let original salary be Rs. x
Then saving = (20/100)x = x/5
Expenditure = (80/100)x = (4x/5)
New income = (140/100)x= (7x/5)
New saving = (20/100)x = (x/5)
New expenditure = (7x/5) – (x/5) = (6x/5)
Increase in expenditure = (6x/5) – (4x/5)
= (2x/5)
Increase % = [(2x/5)/(4x/5)]*100
=50%
