A person bought some Australian dollar of NRs 1,50,000 according to the exchange rate. Australian dollar 1 = NRs 77.02. After fi

Answer:

5.26% profit (NRs 7,894.24)

Step-by-step explanation:

The exchange of 1,50,000 NRs to A$ will give ...

A$ 1/(NRs 77.02) = x /1,50,000

x = A$ 1,50,000/77.02 = A$ 1947.54 . . . . . (rounded down)

If the Nepali rupees are devalued by 5%, then what did buy A$ 1 will now buy only A$ 0.95. Then the exchange back to NRs will give ...

(NRs 77.02)/(A$ 0.95) = x/(A$ 1947.54)

x = NRs (1947.54)(77.02/0.95) = NRs 1,57,894.24

The effective profit is the difference from the amount initially exchanged, NRs 7,894.24, or ...

(1,57,984.24/1,50,000 -1) × 100% ≈ 5.26%

<em>Additional comment</em>

Except for the loss in the exchange due to rounding down, the profit would be 1/0.95 -1 = 5.2632%. Instead, it is 5.2628%. This is why investors move their money to investments that retain their value when the local currency is losing its value.

Musya8 [376]

Assume Alan's brother has x coins before Alan gave him 48 coins
x+48=1.4x (increased by 40%)
0.4x=48
x=120
120+140=260
answer is 260 coins

What is the equation of the line that passes through (1, 2) and is parallel to the line whose equation is 2x + y - 1=0?

elixir [45]

Answer:

y=-2x+4

Step-by-step explanation:

2x+y-1=0

2x+y=0+1

2x+y=1

y=1-2x

y=-2x+1

y=mx+b where m=slope and b=y-intercept

parallel means same slope,

so the slope would still be -2.

--------------

y-y1=m(x-x1)

y-2=-2(x-1)

y=-2x+2+2

y=-2x+4

Find A, B, and C <br> Help ASAP!<br> {10 points up}

Rama09 [41]

so we have a 60-30-90 triangle (top one)

so since we know 6 is x (the side on the right angle and 60 degrees)

b is 2x or 2(6) = 12

a is x√3 = 6√3

for C I need to use a 45 45 90 triangle

Since b is 12 and its x√2 to find x we should write it as

x√2 = 12

√2 √2 divide by √2

x = 12/√2 but we must rationalize the denominator

12/√2 times √2/√2 = 12√2/2 and that's c
