A retailer buys 40 pens at the marked price of 36 pens. If he sells these pens giving a discount of 1%, what is the profit percent?
A. 9%
B. 10%
C. 11%
D. 12%
bbb
solution bhi dena sath me mera maths week h
O-O
B. 10%
Explanation:
Let MP of 1 pen = Re 1
CP of 40 pens = MP of 36 pens = Rs 36
MP of 40 pens = Rs 40
So after discount of 1%, SP of 40 pens = 99/100 * 40 = Rs 39.6
So profit% = (39.6 – 36) / 36 * 100 = 10%
cp=36 sp = 39.6
p% = 3.6/26*100=10%

8. A can cultivate 2/5th of the land in 6 days and B can cultivate 1/3rd of the same land in 10 days. Working together A and B can cultivate 4/5th of the land in how many days?
A) 4 days
B) 5 days
C) 8 days
D) 10 days
ccc
ddd
15*30/45=10 days
4/5 =8 days
C) 8 days
Explanation:
A can cultivate 2/5th of the land in 6 days, so whole land in 5/2 * 6 = 15 days.
B can cultivate 1/3th of the land in 10 days, so whole land in 3/1 * 10 = 30 days.
A and B together can complete whole land in 15*30/(15+30) = 10 days.
So 4/5th land in 4/5 * 10 = 8 days
A does half as much work as B in one sixth of the time. If together they take 10 days to complete a work, how many days shall B take to do it alone?
A) 70
B) 30
C) 40
D) 50
cc
C) 40
Explanation:
Let B do whole work in ‘x’ days.
A does ½ work in x/6 days, so whole work in 2x/6 = x/3 days
Together they take 10 days, so x * x/3 / (x+x/3) = 10
Solve, x = 40 days
Oranges are bought at 7 for Rs 3. At what rate per hundred must they be sold to gain 33%?
A) Rs 56
B) Rs 57
C) Rs 58
D) Rs 60
57?
bbb
B) Rs 57
7 for Rs 3, so for 1 Re oranges are 7/3
So for Re 1 to gain 33%, number of oranges sold = 7/3 * 100/(100+33) = 100/57
So per hundred oranges = 57 Rs

100*3*133/7*100=57
10. The selling price of an article is marked at 20% above the cost price. At the time of selling, he allows a discount of 8%. His profit percent is:
A. 20%
B. 10.4%
C. 8.6%
D. 12%
bb
222b
bbb
B. 10.4%
Explanation:
Use M.P. = (100 + p%)/(100 – d%) * C.P.
MP is 20% above CP.
120/100 C.P. = (100 + p%)/(100 – 8) * C.P.
solveing we get
p = 10.4%
100*6/5*92/100=110.4
The ratio of income of A and B is 2:3. The sum of their expenditure is Rs.8000 and the amount of savings of A is equal to the amount of expenditure of B.What is the their ratio of sum of income to their sum of savings?
A.5:3
B.3:2
C.4:3
D.3:1
E.None of these
sol??? mujhe to nhi ata ye
Answer A.5:3
Explanation :
2I-E + E = 8000
I = 4000
Sum of their Income = 5*I = 5*4000 = 20,000
Sum of their Savings = 20000-8000 = 12,000
20000:12000 = 5:3
2I-E + E = 8000
line samaj nhi aayi
2i = sum of income
sum of saving of one is = sum of expenditure of other so 2e taken

There are two numbers. When 25% of the first number is added to the second number, the resultant number is 1.5times th first number.What is the ratio of 1st number to the 2nd number ?

C.4:5
D.2:3
E.None of these

Answer – C.4:5
Explanation :
A+25/100 + B = 1.5A
A/4 + B = 15A/10
10A+40B/40 =60A/40
10A+40B = 60A
50A = 40B
A/B = 4/5

y = 9/2 , 4
aa rha hai na
hmm mene 7 ko 2 le liya tha so wrong ho gya mera
kuch dikh nhi rha mujhe ???
111
A. x ≤ y
Explanation:
7×2 – 43x + 60 = 0
7×2 – 28x – 15x + 60 =0
7(x-4) – 15(x-4) = 0
x = 4, 15/7
2y2 – 17y + 36 = 0
2y2 – 8y – 9y + 36 = 0
2(y-4) – 9(y-4) = 0
y = 4, 9/2

kese sol karete yese ques
plz tips do
mujhe bhi ni ata ye but ese shayd 45+20+30-40=55
100-55=45%
ty 🙂
failed in both= 20%
means fail in only hindi=30-20=10%
fail in only eng =45-20=25%
means fail in atleast 1 subject =20+10+25=55%
remaining students are passed in both subject=100-55=45%

8. A car owner buys petrol at Rs 4, Rs 5 and Rs 6 per litre for three successive years. What approximately is the average cost per litre of petrol if he spends Rs 2400 each year?
A. Rs 4.86
B. Rs 4
C. Rs 5
D. Rs 6
ye kaise hoga ??????
aa?
aaa
avg cost = total amount spend on petrol/ total quantity of petrol
petrol quantity in year 1=2400/4=600 L
Q2=2400/5=480L
Q3=2400/6=400L
avg cost=3*2400/(600+480+400)=4.86

BTA DO KK SRY 🙁
ans nhi pta
BOTH ??
both needed
how.
let mp=x
15% discount on mp
so sp=x*75/100=3x/4
cp=3x/4-16
in stmt II, mp-sp=(sp-cp)+50
x-3x/4=(3x/4-(3x/4-16))+50
solve this /
correct???
solve aap hi krke do

aapne 10% kyu liya
mai galti se kar diya…but method ye hi hai…
thanx..
15% discount
ohoo..hn wese hi hoga…mai 75 ka kar diya
method yehi hai..but solution galat hai mera
neither hona chahye
sir kese?
statement 1 se suppose
MP=100x
SP= 85x
CP=85x-16
2nd se
MP-CP=3/2(SP-CP)
15x=3/2 16
find x and get MP
so both
yes sir,,,mera 2nd stmt ka equation galat tha,, sry
thank u

After replacing an old member by a new member, it was found that the average age of four members of a family is the
same as it was 3 year ago. What is the difference between the ages of the replaced and the new member ?
After I originally commented I clicked the -Notify me when new comments are added- checkbox and now every time a remark is added I get 4 emails with the identical comment. Is there any manner you may take away me from that service? Thanks!
Great post. I was checking continuously this blog and I’m impressed!
Extremely useful information specially the remaining phase 🙂 I take care of
such info much. I used to be looking for this particular information for a long time.
Thank you and best of luck.
I have been browsing online more than 2 hours today, yet I never found
any interesting article like yours. It is pretty worth enough for me.
In my opinion, if all site owners and bloggers made good content as you did, the web will be much more useful
than ever before.
