after paying income 5% a man has Rs 7600 left. what is his income?
Answers
Answer:
His income was 8000 rupees
Step-by-step explanation:
We must find his income so let that be x
We take 100%-5% = 95%
Turn this 95% into a decimal which is 0.95
So:
x * 0.95 = 7600
Rearrange this to give x:
x = 7600/0.95
x = 8000 rupees
The man's income is Rs. 8000. He has been left with 95 percent of his income = Rs. 7600.
What are percentages?Percentages are fractional values where the total amount is taken as 100.
25% of a quantity means 25/100 of that quantity.
How to solve the given question?In the question, we are informed that after paying 5% of income, a man is left with Rs. 7600.
We are asked to find his income.
We are given that a man pays 5% of his income, so he will be left with (100-5)% = 95% of his income as percentages are taken over a total of 100.
We assume the man's total income to be Rs. Y.
∴ We can say that the man is left with 95% of Y.
We know the man is left with Rs. 7600. So we can write this case as:
95% of Y = 7600
or, 95/100 of Y = 7600
or, (95/100)*Y = 7600
or, Y = (7600*100)/95 = 760000/95 = 40000/5 = 8000.
∴ The man's income is Rs. 8000. He has been left with 95 percent of his income = Rs. 7600.

Little Johnny is fleeing from a horde of zombies. He is 4000 feet from a safe zone where a gate will be closed in 3 minutes. If Johnny is running at a rate of 22 mph, will he be able to reach the safe zone before the gate is closed? Yes or No? Explain BRIEFLY.
Answers
Answer:
Johnny will be able to reach the safe zone before the gate is closed.
Step-by-step explanation:
Given that:
Distance of Little Johnny from safe zone = 4000 feet
Time = 3 minutes
Speed = 22 mph
To find:
Will Johnny be able to reach the safe zone ?
Solution:
Johnny can only be safe if he can travel 4000 feet in 3 minutes with the given speed.
Let us try to find out, the distance that he can travel in 3 minutes at speed of 22 mph.
Let us have a look at the formula of distance traveled:
[tex]Distance = Speed \times Time[/tex]
Time = 3 minutes = [tex]\frac{3}{60}[/tex] hrs
Speed = 22 mph
[tex]Distance = 22 \times \frac{3}{60}\\\Rightarrow Distance = \dfrac{22}{20}\ miles \\\Rightarrow Distance = 1.1\ miles[/tex]
We know that 1 mile = 5280 feet
Therefore 1.1 miles = 5280 [tex]\times[/tex] 1.1 feet = 5808 feet
Distance traveled by Little Johnny is greater than 4000 feet.
Therefore Johnny will be able to reach the safe zone before the gate is closed.

An item is on sale for $100. If it was discounted by 20%, what was the original selling price?
Answers
Answer: The original price was $125
Step-by-step explanation:
If an item is on sale for $100 and it was discounted by 20% then we could set up an equation and solve for the original price.
Remember if there were 20% discount then 80% of the price will be left.
80% * x = 100
0.8x =100
x = 125
Step-by-step explanation:
We have :
• Selling Price = $100
• discount = 20%
As we know
• Selling Price = Cost - Discount
Now we have
• Discount = 20%
Let cost be x
→ Selling Price = x - 20% of x
→ selling price = 80% of x
→ 80% of x = 100
→ 80/100 x = 100
→ x = 100 × 100 / 80
→ x = $ 125

To solve this equation for x, we simply need to apply equation operations and isolate the x variable.
cx - 4 = 7
cx - 4 + 4 = 7 + 4
cx = 7 + 4
cx = 11
cx * (1/c) = 11 * (1/c)
x = 11 * (1/c)
x = 11/c

find the 40th term of an AP where 12th term is 45 and 17th term is 80.
Answers
Answer:
40th term = 241.
Step-by-step explanation:
17th term:
= a1 + 16d = 80
12th term
= a1 + 11d = 45 Subtracting the 2 equations:
5d = 80 - 45 = 35
d = 7
and a1 + 16(7) = 80
a1 = 80 -112 = -32.
Therefore the 40th term = -32 + 39*7
= 241.
