Q5. The Cost Price Of A Bed Is Rs.2400 Which Is 20% Below The Market Price If It Is Sold At A Discount Of sixteen% On The Market Price Then Find Its Market Price, Selling Price And Profit ?
Cost fee of mattress= Rs.2400

C.P= eighty*X/a hundred -> 2400=eight*X/10
X = Rs.3000.
-> S.P = 3000 ? (sixteen*3000)/a hundred
Selling Price = 2520
-> Profit = 2520- 2400 ==> 120Rs.
%income = 120*100/2400= 5%

Q13. P, Q And R Are Three Typists Who Working Simultaneously Can Type 216 Pages In four Hours. In One Hour, R Can Type As Many Pages More Than Q As Q Can Type More Than P. During A Period Of Five Hours, R Can
Let's the wide variety of pages typed in one hour by means of P, Q and R be p, q and r respectively. Then,
P,Q and R typed page in 1 hrs = 216/4
=> p + q + r = 216/4
=> p + q + r = fifty four ...(i)
r - q = q - p => 2p = q + r ...(ii)
5r = 7p => p = five/7 r ...(iii)
By Solving above (i), (ii) and (iii) equations
=> p = 15, q = 18, q = 21

Q16. If A Man Travels With 5/6th Of His Usual Speed, He Is Late By 15 Mins. What Is The Usual Time Taken To Travel ?
Suppose guy's common velocity = s, and common time = t
So distance = speed *time ==> d= s*t
If he travels with five/6th of his normal velocity that's = s*5/6
And time= (t+15) and distance, d = (s*5/6)*(t+15) as distance could be same
s*t = (s*five/6)*(t+15)
t= 75 min.

Q18. Find The Value Of (483*483*483+ 517*517*517) / (517*517 - 517*483 + 483*483) ?
(483*483*483+ 517*517*517) / (517*517 - 517*483 + 483*483) a3+b3
= (a+b)(a2-ab+b2) Hence [(a+b)(a2-ab+b2)] / (a2-ab+b2)
= a+b In the given equation a=483 and b= 517
==> 483+517=one thousand.
Q19. What Percent Of Selling Price Would Be 34 % Of Cost Price If Gross Profit Is 26 % Of The Selling Price ?
X% of SP = 34% of CP
Also, P = 26% of SP
SP - CP = zero.26(SP)
CP = zero.Seventy four(SP)
Now, (34/100)×seventy four
X = 25.Sixteen
Q20. A' And 'b' Complete A Work Together In 8 Days.If 'a' Alone Can Do It In 12 Days.Then How Many Day 'b' Will Take To Complete The Work?
A & B sooner or later paintings = 1/eight
A by myself in the future work = 1/12
B by myself at some point work = (1/8 - 1/12) = ( 3/24 - 2/24)
=> B at some point work = 1/24
so B can whole the paintings in 24 days.
Q21. Dhruva Gave 35% Of Her Monthly Salary To Her Mother. From The Remaining Salary, She Paid 18% Towards Rent And 42% She Kept Aside For Her Monthly Expenses. The Remaining Amount She Kept In Bank Account

Sum of the phrases of the ratio=2+three+five=10
P-percentage= 210×totalmoney=210×2000=2×2 hundred=Rs.Four hundred
R-proportion= 510×totalmoney=510×2000=five×2 hundred=Rs.A thousand

Q24. The Ages Of Two Persons Are In The Ratio 5:
Let the desired ages be 5x and 7x
18 years ago their age ratios
65x-234=56x-one hundred forty four
65x-56x=234-a hundred and forty four
Thus the a while are 5x=five×10=50years

Q26. A, B And C Started A Business By Investing Rs. 40,500, Rs. 45,000 And Rs. 60,000 Respectively. After 6 Months C Withdrew Rs. 15,000 While A Invested Rs. 45,000 More. In Annual Profit Of Rs. 56,one hundred, Th
For one year the capital is
A = (40500 * 6 + 45000 * 6) = Rs. Five,13,000
B = (45000 * 12) = Rs. 5,40,000
C = (60000 * 6 + 45000 * 6) = Rs. 6,30,000
Ratio A : B : C = 513 : 540 : 630
C's proportion will exceed that of A by means of
= [(630 - 513)/1683] * 56100 => (117/1683) * 56100
=> (117/3) * 100 = 39 * one hundred = Rs. 3900
Q27. Shiva Purchased forty Shirts For Rs.30
Total value price of 40 shirts inclusive of trportation = 3000+ (3000*10)/a hundred = 3300
Given income = 20%
Hence, Selling rate = (100+20)*3300/a hundred
S.P of forty shirts = 3960
So S.P. Of one shirt = 3960/forty= Rs.99
Q28. If 35% Of 30 = 25% Of X + 1, Find The Value Of X ?
35% of 30=25% of X+1
35*30/a hundred= 25*X/100+1
one zero five/10=X/four +1
Q29. In How Many Ways Letters Of World "main" Can Be Arranged, So That Vowels Always Come Together ?
LEADING word may be written as "L" "E" "A" "D" "I" "N" "G"
Taking vowels together = E A I, so vowels may be organized as= !3 approaches and we could Vowels be a unit X
So X L D N G, It may be arranged in = !5 Ways
So whole word can be written in= !Three *! Five = 720 methods
Q30. A And B Can Complete A Work In 30 Days, Working Together. Both Worked For 20 Days And Then B Left The Work. The Remaining Work Was Completed By A Alone In 20 More Days. So In How Many Days B Alone Can
(A+B)'s 1-day work, whilst running together= 1/30
(A+B)'s 20 days' paintings= 20/30==> 2/three
Remaining paintings = (1-2/three) ===> 1/3
Remaining paintings became performed through A in 20 more days = 1/three
So A can entire the entire paintings by myself in = 20* 3 ===>60 days
Hence A's 1-day work, operating alone = 1/60
B?S 1 day paintings, working by myself = 1/30-1/60======1/60
So B will take 60 days to for completing the whole word.
