1.

Given: P = 134, B = 67 , R = ?

Solution:

P = B x R

R = P/B

R = 134 / 67

R = 2 or 200%

2.

Given: R = 20% , B=198, P = ?

P = B x R

P = 198 x 20%

P = 39.6

Estimate 20% of 198, round 198 to 200 then multiply it by 20% = 40

3.

Given:

Amount Deposited = $ 8500

Annual Simple Interest Rate = 6.5%

Amount after 10 years = ?

Solution:

Get the annual interest amount

A = Amount Deposited * Annual Rate

A = $ 8500 * 6.5%

A = $ 552.50 / year * 10 years

Total Interest amount for 10 years = $ 5525.00

Total Amt after 10 years = Principal + Interest Amount

Total = $ 8500.00 + $ 5525.00

Total = $ 14,025.00

4.

Given:

Amount Loan = $ 3500.00

Amount after 4 yrs = $ 4200.00

Rate = ?

Get the Difference of the Amount

Difference = Amount Paid - Principal Amount

Difference = $ 4200.00 - $ 3500.00

Difference = $ 700.00

Interest per year = Difference / No. of Years

Interest/Year = $ 700 / 4

Interest/Year = $ 175.00

In getting the rate/year

P = $ 175.00

B = $ 3500.00

R = ?

P = B * R

R = P / B

R = $ 175.00 / $ 3500.00

R = 0.05

R = 0.05 * 100%

R = 5% per year

5.

Given:

Principal Amount = $ 2250.00

Rate = 3.5%

Total Amount of N Years = $ 2722.50

N Years = ?

Interest Amount/Year = Principal Amount * Interest Rate

Interest Amount/Year = $ 2250.00 * 3.5%

Interest Amount/Year = $ 78.75

Total Interest After N Years = Total Amount - Principal Amount

Total Interest = $ 2722.50 - $ 2250.00

Total Interest = $ 472.50

N of Years = Total Interest / Interest Amt per Year

N of Years = $ 472.50 / $ 78.75

N of Years = 6

(1) 134/67= 2.

Thus, the factor by which 67 needs to be multiplied to get 134 is 2. therefore, 200% of 67 =134.

20/100*198= 3960/100.

You move the decimal point which is after the 0 in 3960 two places to the left.

thus, 20% of 198= 39.60.|||I just show you the way, solve them yourself.

for finding some percent of number, easy do this:

e.g. 10% of 200

( 200 * 10 ) /100 = 20

if you gonna find what percent of 200 is 20 , do like this

200 * ( ) / 100 = 20

so ( ) = 100 * 20 /200

( ) = %10

your other problems are similar.|||1)

134/67 x 100%

= 13400/67 %

= 200%

2)

198 x 20%

鈮?200 x 20/100

= 200 x 1/5

= 200/5

= 40

3)

$8500 x 6.5% x 10 + $8500

= $8500 x 65% + $8500

= $8500 x 65/100 + $8500

= $8500 x 13/20 + $8500

= $110500/20 + $8500

= $5525 + $8500

= $14025

4)

(4200 - 3500)/3500 x 100%/4

= 700/3500 x 100%/4

= 1/5 x 100%/4

= 100/5 %/4

= 20%/4

= 5%

5)

$2250 x 3.5%y + $2250 = $2722.5

$2250 x 3.5y/100 = $2722.5 - $2250

$2250 x 3.5y/100 = $472.5

3.5y/100 = $472.5/$2250

3.5y = $47250/$2250

3.5y = 21

y = 21/3.5

y = 6|||1. 200%

2. 39.6

3. N=8500(1+.065)raised to the power of 10

=8500 (1.877)

= 15954.5 (but when u don%26#039;t cut it down to 3 decimal places in the calculator, u%26#039;ll get 15,955.66

4. 4.66%

5. 5 years and a half.
