Find the sum which amounts to Rs 9261 at 10% per annum compound interest for 18 months ,interest payable half yearly
AleksAgata [21]

Find the sum which amounts to Rs 9261 at 10% per annum compound interest for 18 months ,interest payable half yearly

A=P(1+\frac{r}{n})^{nt} , where A is amount , r is rate =10% = 0.10 , n is intervals of compounding n=2 , t is time = 18 months=1.5 years

Lets plug in

9261=P(1+\frac{0.10}{2})^{2*1.5}

9261 = P(1.002)^{3}

9261 = P(1.006012008)

divide both sides by 1.006012008

P= Rs 9205.6555

The product of a number and ten is twelve more than the product of the number and five-eighths.
ra1l [238]
Let the unknown number be x.

Given,

10 * x = 12 +  \frac{5}{8}  * x

10x = 12 +  \frac{5x}{8}

10x -  \frac{5x}{8} = 12

\frac{(10x*8)-5x}{8} = 12

80x-5x =12*8

75x = 96

x = \frac{96}{75} = 1.28

Hence, the number is 1.28

Nadusha1986 [10]

Answer:

x=\frac{18000}{7}=2571\frac{3}{7}

Step-by-step explanation:

Let the total amount be x

Then Ali got 1/8x With 7/8x left

Juma got 7/40x with 7/10x left

Musa, Khalid and Mustafa got 7/30x each

since \frac{7}{30}x=600

7x=18000

x=\frac{18000}{7}=2571\frac{3}{7}
