10%he kept for auto left with him is 180
he bought 20mangoes ie.=100rs

2. BABA JEE

Q2 100 increase by 30% = 130 then decreases by 20% = 104 HENCE ans = 4%

3. rana

50Or=40M
5Or=4M
so 10%40M=4M so that means he can buy 36M
he bought 20M
so more he can buy 16M

1. Sahil Khaneja

2. Jitesh Kumar Singh

no, its correct
55 * 65 * 20 = 65 * 70 * x
x = 110/7

% = [(20 – 110/7)/20 ] * 100
Ans -> approx 21%

4. BABA JEE

Can anyone explain question no. 4 ?

1. Jitesh Kumar Singh

I took total no. of voters = 100
for P there are 40 voters and 15% went back, they went back promises so 6 left for Q,
for Q there are 60 voters and 25% went back, they went back promises so 15 left for P
for P there are 34 + 15 = 49
for Q there are 45 + 6 = 51

So, the difference is 2.

7. prapti dutta

plz solve q.8 for me sum1?

8. Niketan Moon

Total increase in the price of sugar = (8 +2)=10
Now for first year,
price of sugar = 20 + 20*0.1= 22
For the second year,
New price of the sugar = 22
10% increase = 2.2′
Therefore the total price in 1996 will be 22+2.2=24.2(Ans)

9. Niketan Moon

#8
Ans (D) Correct
Since minimum required % so that C will pass is atleast 28%
Anything greater than that will do.
Assume total marks =100
Passing marks = 40
A marks = 36
B marks= 32.01
Now sum of A+B = 68.01
So for C to pass the exam,He can score 28.01 marks less
i.e 68.01 – 40
Therefore Minimum percentage will be 28%
and anything greater than that will also make C qualify.

13. ROHIT

can anyone explain que no. 5?

14. Naveen Kumar chaurasia

5.let x votes got and y did not get by party,
x+y=260000=A
x-y=z win by z votes in previous election
party did not get 1.25y vote this time and got A-1.25y votes
1.25y-(A-1.25y)=2z lost by twice that it had won
y=(4x+2A)/9
x=7A/13
x=140000

#2 use effective percentage formula

16. Shubhangi Verma

When total income is Rs. 4000, a man earns x% on first Rs.2000 and y% on Rs.2000.

2000x/100 + 2000y/100 = 700

When total income is Rs. 5000, a man earns x% on first Rs.2000 and y% on Rs.3000.

2000/100 + 3000y/100 = 900

The equations can be simplified to

x + y = 35 and 2x + 3y = 90

Solving these two equations simultaneously, x = 15%.
