Five years ago, Nina was twice as old as Sam. In five years, she will be 1.5 times as old as Sam. How old are Nina and Sam now?

Margarita [4]

Answer:

age of Sam= 15 years

age of Nina = 25 years

Step-by-step explanation:

Let Nina's age be X years

Let Sam's age be Y years

Five years ago Nina's age will be X- 5 years

Five years ago Sam's age will be Y- 5 years

Given in question

Five years ago, Nina was twice as old as Sam

writing it mathematically using X and Y we have

Nina's age = 2 * Sam's age

X- 5 = 2 *(Y- 5)

X = 2 *(Y- 5) + 5 = 2Y - 10 + 5 = 2Y - 5 _________________equation A

__________________________________________________________

Five years in future Nina's age will be X+ 5 years

Five years ago Sam's age will be Y+ 5 years

Given in question

In five years, she will be 1.5 times as old as Sam

writing it mathematically using X and Y we have

Nina's age = 1.5 * Sam's age

X+5 = 1.5 *(Y+ 5)

X = 1.5*(Y+5) -5 = 1.5Y +7.5 - 5 = 1.5Y +2.5 _________________equation B

_______________________________________

in equation A we have X = 2Y - 5

in equation B we have X = 1.5Y + 2.5

equating equation A and B we have

2Y - 5 = 1.5Y +2.5

=> 2Y - 1.5Y = 2.5 + 5

=> 0.5Y = 7.5

=> Y = 7.5/0.5 = 15

from equation A we have

X = 2Y - 5 (substituting the value of Y = 15 in equation we have)

X = 2*15 - 5 = 25

Therefore age of Sam= 15 years

age of Nina = 25 years

what was the original principal for an 8% simple interest bank account that holds $4340 after 3 years?

Solnce55 [7]

Answer:

The original deposited amount in the bank is $3500.

Step-by-step explanation:

Here. Let us assume the principal amount deposited in bank = $P

The rate of interest = 8%

Total Amount in the bank after time period = $4340

Time Period = 3 yrs

Now, SIMPLE INTEREST $= \frac{P \times R \times T}{100}$

⇒ SI = $SI = \frac{P \times 8 \times 3}{100} = 0.24P$

or Interest = 0.24 P

Now, AMOUNT = PRINCIPAL + INTEREST

⇒$4340 = P + 0.24 P

or, 4340 = 1.24 P

⇒ P = 1340 / 1.24 = 3500

Hence, the deposited amount in the bank for the duration of 3 years and interest rate 8% is $3500
