IAS question - ❓❓❓❓❓❓A man starts frm his house with some money to visit four temples.1. As soon as he enters temple 1 his money
Natali5045456 [20]

Answer:

Rs 93.75

Step-by-step explanation:

Solution:

A man starts from his house with some money to visit four temples.

<u>1. As soon as he enters temple 1 his money gets doubled. </u>

Let he had money at first = x

After enter the 1st temple his money = 2x

He donated = Rs 100

Money left after donation at 1st temple = 2x-100

<u>2. At temple 2 again his money is doubled and he donates Rs 100</u>

He had at 2nd temple = 2(2x-100) =4x-200

Donated = Rs 100

Money left after donation at 2nd temple = 4x-200-100=4x-300

<u>3. His money is doubled again at temple 3 and he donates Rs 100.</u>

He had at 3rd temple = 2(4x-300)=8x-600

Donated = Rs 100

Money left after donation at 3rd temple = 8x-600-100=8x-700

<u>4. At temple 4 again his money gets doubled. He donates 100 rs. again and returns home empty handed.</u>

He had at 4th temple = 2(8x-700)= 16x-1400

Donated = Rs 100

Money left after donation at 4th temple = 16x-1400-100 = 16x-1500

<u>As he returned empty hand or with zero money, equation will be:-</u>

16x-1500=0\\ \\ Adding\ both\ sides\ by\ 1500\\ \\ 16x=1500\\ \\ Dividing\ both\ sides\ by\ 16\\ \\ x=Rs \ 93.75

Thus, he had Rs 93.75 when he started from his house.

Suppose a+b = 2aa+b=2aa, plus, b, equals, 2,
Trava [24]
B-a=0.

Starting from the original equation, 
a+b=2a

We can isolate b by subtracting a from both sides:
a+b-a=2a-a
b=a

Substituting this into b-a, we have
a-a = 0

What’s the answer to this
pantera1 [17]

Answer:

A

Step-by-step explanation:

Given f(x) the f(x) + c represents a vertical translation of f(x)

• If c > 0 then a shift up of c units

• If c < 0 then a shift down of c units

Here c = - 6, thus a shift down, thus

g(x) = x² - 6  → A

Use the graph to write the factorization of x^2+2x-8
kozerog [31]

Answer:

(x-2)(x+4)

Step-by-step explanation:

So it would be A.

Explanation: The middle number is 2 and the last number is -8.

Factoring means we want something like

(x+_)(x+_)

Which numbers go in the blanks?

We need two numbers that...

Add together to get 2

Multiply together to get -8

Can you think of the two numbers?

Try -2 and 4:

-2+4 = 2

-2*4 = -8

Fill in the blanks in

(x+_)(x+_)

with -2 and 4 to get...

(x-2)(x+4)

Answer:

(x−2)(x+4)
