of the voters promise to vote for P and the rest promised to vote for Q. Of these, on the last day 15% of the voters went back of their promise to vote for P and 25% of voters went back of their promise to vote for Q, and P lost by 2 votes. Then the total number of voters is

A
100
B
110
C
90
D
95
Answer key/Solution
Solution:
Let there be 100 voters in all.
Initially, 40 of these promised to vote for P, while 60 of them promised to vote for Q.
On the last day, (15% of 40) = 6 voters went back of their promise and voted for Q.
Also, 25% of 60 = 15 voters shifted their interest from Q to P.
So finally, P end up getting (40 – 6 + 15) = 49 votes and Q end up getting (60 – 15 + 6) = 51 votes.
Hence, margin of victory for Q = (51 – 49) = 2, which is true. Hence, there were 100 voters in all.

I bought 5 pens, 7 pencils and 4 erasers. Rajan bought 6 pens, 8 erasers and 14 pencils for an amount which was half more what I had pai(d) What per cent of the total amount paid by me was paid for the pens?

A
37.5%
B
62.5%
C
50%
D
None of these
Answer key/Solution
Solution:
Let us look at the two equations. Let (5 pens + 7 pencils + 4 erasers) cost Rs. x. Hence, (6 pens + 14 pencils + 8 erasers) will cost Rs. 1.5x. Had, in the second case, Rajan decided to buy 10 pens instead of 6, the quantity of each one of them would have doubled over the first case and hence it would have cost me Rs. 2x. So (10 pens + 14 pencils + 8 erasers) = Rs. 2x. Now subtracting the second equation from the third, we get 4 pens cost Rs. 0.5x. Since 4 pens cost Re 0.5x, 5 of them will cost Re 0.625x. This is the amount that I spent on pens. Hence, fraction of the total amount paid = 0.625 = 62.5%.

A

B

C
75
D

Answer key/Solution
Solution:
Since Ghosh babu distributed his property equally among his 4 daughters, each one of them should get 25% of the property. The eldest daughter got 20% of the total property and Rs.25000 in cash. So, Rs.25000 should constitute 5% of the total property. Hence the total property is worth Rs.5 lakhs. Now, the total cash given by him = Rs.25000 (eldest daughter) + Rs.50000 (second daughter) + Rs.150000 (i.e. Rs.75000 each to his third and fourth daughters) = Rs.225000. So, out of his total property of Rs.500000, Rs.225000 is cash, so the gold and silver should be worth Rs.275000.

The salaries of three friends Sita, Gita and Mita are initially in the ratio 5 : 6 : 7, respectively. In the first year, they get salary hikes of 20%, 25% and 20%, respectively. In the second year, Sita and Mita get salary hikes of 40% and 25%, respectively, and the salary of Gita becomes equal to the mean salary of the three friends. The salary hike of Gita in the second year is

A
26%
B
28%
C
30%
D
25%
Answer key/Solution
Solution:
Let the initial salaries of Sita, Gita and Mita be 5x, 6x and 7x respectively.
Then, in first year their salaries will be 5x × 1.2, 6x × 1.25 and 7x × 1.2 i.e., 6x, 7.5x and 8.4x respectively.
In second year salaries of Sita and Mita will be 6x × 1.4 and 8.4x × 1.25 i.e., 8.4x and 10.5x respectively.
In second year, salary of Gita = (8.4x + 10.5x)/2 = 9.45x
Hence, in second year the percentage increase in salary of Gita = (9.45x – 7.5x)/7.5x × 100 = 26%.

Solution:
Let there be 100 voters in all.
Initially, 40 of these promised to vote for P, while 60 of them promised to vote for Q.
On the last day, (15% of 40) = 6 voters went back of their promise and voted for Q.
Also, 25% of 60 = 15 voters shifted their interest from Q to P.
So finally, P end up getting (40 – 6 + 15) = 49 votes and Q end up getting (60 – 15 + 6) = 51 votes.
Hence, margin of victory for Q = (51 – 49) = 2, which is true. Hence, there were 100 voters in all.

Solution:
Let us look at the two equations. Let (5 pens + 7 pencils + 4 erasers) cost Rs. x. Hence, (6 pens + 14 pencils + 8 erasers) will cost Rs. 1.5x. Had, in the second case, Rajan decided to buy 10 pens instead of 6, the quantity of each one of them would have doubled over the first case and hence it would have cost me Rs. 2x. So (10 pens + 14 pencils + 8 erasers) = Rs. 2x. Now subtracting the second equation from the third, we get 4 pens cost Rs. 0.5x. Since 4 pens cost Re 0.5x, 5 of them will cost Re 0.625x. This is the amount that I spent on pens. Hence, fraction of the total amount paid = 0.625 = 62.5%.

Solution:
Since Ghosh babu distributed his property equally among his 4 daughters, each one of them should get 25% of the property. The eldest daughter got 20% of the total property and Rs.25000 in cash. So, Rs.25000 should constitute 5% of the total property. Hence the total property is worth Rs.5 lakhs. Now, the total cash given by him = Rs.25000 (eldest daughter) + Rs.50000 (second daughter) + Rs.150000 (i.e. Rs.75000 each to his third and fourth daughters) = Rs.225000. So, out of his total property of Rs.500000, Rs.225000 is cash, so the gold and silver should be worth Rs.275000.

Solution:
Let the initial salaries of Sita, Gita and Mita be 5x, 6x and 7x respectively.
Then, in first year their salaries will be 5x × 1.2, 6x × 1.25 and 7x × 1.2 i.e., 6x, 7.5x and 8.4x respectively.
In second year salaries of Sita and Mita will be 6x × 1.4 and 8.4x × 1.25 i.e., 8.4x and 10.5x respectively.
In second year, salary of Gita = (8.4x + 10.5x)/2 = 9.45x
Hence, in second year the percentage increase in salary of Gita = (9.45x – 7.5x)/7.5x × 100 = 26%.
