Ramakant spends 40% of the total income (let's say 'x') on food.
40% of x = Rs. 38,400

x = Rs. 96,000
He spends 50% on clothes.
Amount spent on clothes = 96,000/2 = Rs. 48,000
48,000 is the 60% of the marked price of clothes.
So, market price of clothes 

That is, Ramakant gets a discount of Rs. (40% of 80,000) on clothes.
Total discounted money = Rs. 32,000

Since we don`t know the maximum marks, we cannot find the answer.

Let's say that the male population is 300.
Let's say that the female population is 200.
Graduate male population

Graduate female population 

Non-graduate population = 500 - 110 = 390
Percentage of non-graduate population 

Value of machine after 3 years 

The bonus amount of Rs. 1000 increases his savings by 10%.
Since 1000 is 10% of 10,000, the previous month's savings were Rs. 10,000.
Now, as his previous month savings were Rs. 10,000,
Expenses = 15,000 – 10,000 = Rs. 5000

The given information is shown on two different scales as given below:

Difference of percentages of total marks = (6 + 2)
10% (40 - 30) of maximum marks = 8
Maximum marks = 80
Passing marks = 30% of 80 + 6 or 40% of 80 - 2 = 30

Each box contains 114 non-defective bulbs.
∴ 2000/114 = 17.54
So, the company has to purchase a minimum of 18 boxes to meet its requirement of bulbs.

Let 'x' be the salary and 0.6x be the expenses.
In April, the expenses increase by 10% and become 0.66x.
So, the savings decrease by 0.06x, and it is equal to 120.
Therefore, 0.06x = 120
⇒ x = $2000
