IBPS PO General Awareness: Percentages questions with solutions

Q1. Monthly income of P is ₹11,000 more than that of Q. P and Q spent 15% and 10% of their respective monthly incomes on rent, while each spent 10% of his respective monthly income on household items. If the remaining amount they saved and P's saving is ₹7,000 more than Q's, then find the monthly income of Q (in ₹).

1. 15000
2. 36000
3. 25000
4. 24000

Answer: 25000

P spends 25% of income, so saves 75%; Q spends 20%, so saves 80%. Let Q’s income be x, then P’s income is x + 11000. Given P saves ₹7000 more than Q, 0.75(x+11000) = 0.80x + 7000. Solving gives x = 25000.

Q2. What will come in place of the question mark (?) in the given equation? 55% of (120 + 200) - ? = 145% of 300

1. -259
2. -223
3. -252
4. -200

Answer: -259

55% of 320 = 176 and 145% of 300 = 435. So 176 - ? = 435, which gives ? = 176 - 435 = -259. Therefore, the missing value is -259.

Q3. P's salary is 40% more than Q's salary. R's salary is $\tfrac{3}{4}$ of Q's salary. Now the salaries of P and Q are increased by 5%, and the salary of R is increased by 8%. After the increment, what percent of P's salary is R's salary?

1. 56.78%
2. 53.57%
3. 18.66%
4. 55.10%

Answer: 55.10%

Let Q = 100. Then P = 140 and R = 75. After increments, P = 147 and R = 81. So R as a percentage of P is $\frac{81}{147}\times 100 = 55.10\%$. Hence, the correct answer is 55.10%.

Q4. A man spends 20% of his income on rent and 25% of the remaining amount on clothes, and the remaining income is invested in FD and RD in the ratio 1:4, respectively. If the difference between the amount invested in FD and the amount spent on clothes is ₹1680, then find the man's income (in ₹).

1. 26000
2. 24000
3. 21000
4. 23000

Answer: 21000

After rent, 80% of income remains. Clothes take 25% of that, i.e. 20% of income. The remaining 60% is split in the ratio 1:4, so FD = 12% of income. The difference between clothes and FD is 8% of income = 1680, giving income = 21000.
