Options:
(a) 5/8  (b) 5/4  (c) 3/8  (d) 7/18

Answer: (a) 5/8

Explanation:
Let total employees = 100
→ Women = 60, Men = 40
→ Employees earning ≥ ₹20,000 = 60% of 100 = 60
→ Women earning ≥ ₹20,000 = 75% of 60 = 45
→ Men earning ≥ ₹20,000 = 60 – 45 = 15
→ Men earning < ₹20,000 = 40 – 15 = 25
Required fraction = 25/40 = 5/8

Question 2: Rahul spends 50% of his monthly income on household items, 20% on clothes, 5% on medicines, and saves ₹11,250. What is Rahul’s monthly income?

Options:
(a) ₹38,200  (b) ₹34,000  (c) ₹41,600  (d) ₹45,000

Answer: (d) ₹45,000

Explanation:
Let Rahul’s income = 100 units
Savings = 100 – (50 + 20 + 5) = 25 units
Given 25 units = ₹11,250
1 unit = 11,250 / 25 = ₹450
Income = 100 × 450 = ₹45,000

Question 3: The marked price of a laptop is ₹48,750. A shopkeeper offers two successive discounts of 10% and x% and sells it for ₹40,365. Find x.

Options:
(a) 5%  (b) 8%  (c) 10%  (d) 9%

Answer: (b) 8%

Explanation:
After first discount: 48,750 × (90/100) = 43,875
Selling Price = ₹40,365
Discount amount (2nd) = 43,875 – 40,365 = 3,510
x = (3510 / 43,875) × 100 = 8%

Question 4: Anish spent 20% of his money on a new phone and 15% of the remaining on a laptop. Then he donated ₹160 and was left with ₹1,200.
How much did he spend on the laptop?

Options:
(a) ₹220  (b) ₹240  (c) ₹320  (d) ₹350

Answer: (b) ₹240

Explanation:
Let total money = X
After spending 20% and then 15% of the remaining:
Remaining fraction = (80/100) × (85/100) = 0.68
Remaining before donation = 1,200 + 160 = 1,360
0.68X = 1,360 → X = 2,000
Amount spent on laptop = 2,000 × (80/100) × (15/100) = ₹240

Question 5: Akshara decided to donate 15% of her salary to an orphanage. She finally donated ₹2,896, which was 90% of what she had planned. Find her salary.

Answer: (c) ₹21,450

Explanation:
Let salary = x
Decided donation = 15% of x
Actual donation = 90% of decided = ₹2,896
x × (15/100) × (90/100) = 2,896
x = (2,896 × 100 × 100) / (15 × 90) ≈ ₹21,450

Options:
(a) 72%  (b) 67%  (c) 66%  (d) 60%

Answer: (b) 67%

Explanation:
Total = 300 + 200 = 500
Target = 46% of 500 = 230
Science = 32% of 300 = 96
Needed in Language = 230 – 96 = 134
Required % = (134 / 200) × 100 = 67%

Question 7: In a village, 60% of families have a cow, 30% have a buffalo, and 15% have both. If there are 96 families, how many have neither?

Options:

= (25/100) × 96 = 24 families

Options:
(a) 50%  (b) 28%  (c) 75%  (d) 26%

Answer: (d) 26%

Explanation:
Let total = 500 → Boys = 400, Girls = 100
Boys without scholarship = 25% of 400 = 100
Girls without scholarship = 30% of 100 = 30
Total = 130 → (130 / 500) × 100 = 26%
