In a election between two parties P and Q, Q is loser. If Q get 25% more votes then he win by the thrice the majority then that of P. If the total number of votes are 4250. How many vote did P get? 1)2250 2)1125 3)2000 4) 1525.. please give solution

3) 2250

Total votes = P + Q = 4250 ---(i)
When Q is loser, majority of P = (P - Q)
When Q gets 25% more votes, then votes of Q = Q + 0.25Q = 1.25Q and votes of P = (P - 0.25Q)
According to given condition, 1.25Q - (P - 0.25Q) = 3*(P - Q)
=> 4P - 4.5Q = 0 ---(ii)
On solving equations (i) & (ii), Q=2000, P=2250

In a local election, 2400 people were to vote for Party A or Party B. Party A was bound to win the election. However, on Election Day, 33% of the voters of Party A were kidnapped. Party B was also able to influence the remaining Party A voters and thus double the strength of its voters. In this way, Party A lost by a majority which was half of that by which it would have won had the elections been fair. How many people finally voted for Party A and Party B?

Devendra Marghade 4 years ago

Final voters of party A=1029, B=1371

In fair election, party A voters=1542, party B voters=858, majority of A=684
After 33% and some voters of A shifted to B, Party A voters=1029, party B voters=1371, majority of B=342

The ratio of A and B’s income last year was 4:3 the ratio of their own incomes of last year and this year individually, it’s 3:4 and 5:6 respectively. If the total sum of their present income is ₹8.04 lakh, then what is the last year income of b? Please give solution

Reply Like? Yes (2) | No

Devendra Marghade 4 years ago

2.7 lakh

Let the income of A & B last year was 4x and 3x.
Given ratio of their last year to this year income individually are 3:4 and 5:6 respectively.
Then income this year of A = 4x*(4/3) = 16x/3 and income of B = 3x*(6/5) = 18x/5
Sum of the incomes this year = 16x/3 + 18x/5 = 804000
=> x = 90000
Therefore, last year income of B = 3x = 3*90000 = 270000 = 2.7 lakh

Let the total time taken be 'x' hrs.
Then, for x/2 hrs pipe B fills at 1/20 per hr and for remaining x/2 hrs both pipes A & B fills at (1/30 + 1/20) per hr.
(x/2)*(1/20) + (x/2)*(1/30 + 1/20) = 1

Let C takes 'x' days, then A takes 3x days and B takes 3x/2.
1 day work of A , B & C = 1/3x + 1/(3x/2)+ 1/x = 1/2
=> x=4
Therefore, A takes 12 days and B takes 6 days to do the work alone.

1.2/3rd of the balls in a bag are blue, the rest are pink. if 5/9th of the blue balls
and 7/8th of the pink balls are defective, find the total number of balls in the bag
given that the number of non defective balls is 146?

Devendra Marghade 5 years ago

432

Let total balls be x. Blue=2x/3, Pink=x/3
Defective balls = (5/9)*(2x/3) + (7/8)*(x/3) = 143x/216
Non defective balls = x - 143x/216 = 73x/216
Given non defective balls are 146, so 73x/216 = 146 => x=432

sagar 5 years ago

Let total balls in the beg are x
Then Blue balls in the beg are = 2x/3
Pink balls in the beg are = 1-2x/3=x/3
Defective blue balls= 5/9 (2x/3)
Defective pink balls= 7/8 (x/3)
Total Defective balls in the beg are= 143x/216
Hence total non defective balls in the beg are = x-143x/216=73x/216
Given that total defective balls in the beg are 146
Hence 73x/216=146
i.e. X= 432 Balls

Yashi Das 5 years ago

Let the total numbers of the ball in a bag be x.

Blue balls = 2/3 of x

Pink ball = x - 2x/3

= x/3

Now,

Defective Blue balls = 5/9 of (2/3 of x)

= 5/9 × 2/3 × x

= 10/27 × x

Defective Pink balls = 7/8 of x/3

= 7x/24

Now, Defective Blue and Pink balls = 146

10x/27 + 7x/24 = 146

(80x + 63x)/216 = 146

∴ 143x = 146 × 216

x = 220.53

= 221 balls.
