At the school carnival, students are asked to guess the number of marbles in a jar to win a prize. There are 240 marbles in the

Lapatulllka [165]

There is 17% error in the guess.

Step-by-step explanation:

Given,

Number of marbles in jar = Exact value = 240

Closest guess = Approx Value = 280

Percent error = $\frac{|approx-exact}{exact}*100$

Percent error = $\frac{|280-240|}{240}*100\\$

Percent error = $\frac{|40|}{240}*100$

Percent error = $\frac{4000}{240}=16.67\%$

Rounding off to nearest whole percent

Percent error = 17%

There is 17% error in the guess.

B. In what time will Rs 10000 will yield a compound interest of Rs 2769

taurus [48]

Answer:

after 8years

Step-by-step explanation:

Complete question;

In what time will Rs 10000 will yield a compound interest of Rs 2769 at 3% per annum

Using the compound interest formula;

A =P(1+r)^n

Given

P = Rs10000

A = 10000+2769

A = 12769

rate = 3% = 0.03

Substitute and get the time t

12769 = 10000(1+0.03)^n

12769/10000 = 1.03^n

1.2769 = 1.03^n

log 1.2769 = nlog1.03

n = log 1.2769/log 1.03

n = 0.1062/0.01283

n = 8.27

Hence the time is approximately after 8years
