Answer 1

Answer:

Step-by-step explanation: This answer is according to me and what I have learned,

The ratio is: 2:1:3

so let the common multiple be $x$. Therefore,

2$x$+1

6$x$=18000

$x$=$\frac{18000}{6}$

therefore $x$=3000

therefore,

expense on education=2$x$=2×3000=Rs.6000

savings =$x$=1×3000=Rs.3000

miscellaneous=3$x$=3×3000=Rs.9000

DONE!

Percentage,

education=$\frac{6000}{18000}$×100=33.3%

similarly,

savings=16.7%

misc.=50%

Answer 2

The respective percentages are $33\dfrac{1}{3}\%,16\dfrac{2}{3}\%,50\%$

Amount = Rs. 18000

Ratio for education , saving and other expensive = 2:1:3

So, Usage of income on education is given by

$\dfrac{2}{6}\times 100=33\dfrac{1}{3}\%$

Usage of income on saving is given by

$\dfrac{1}{6}\times 100=16\dfrac{2}{3}\%$

Usage of income on expensive is given by

$\dfrac{3}{6}\times 100=50\%$

Hence, the respective percentages are $33\dfrac{1}{3}\%,16\dfrac{2}{3}\%,50\%$
