Given that the angles of a triangle are in the ratio 5:4:3 Let the numbers x Now 5x + 4x + 3x is equal Now,12x = 180 So, x =180/12 = 15 5×= 15×5 =75 4×=15×4= 60 3x =15×3= 45 Now the required ratio is equal to 75 is to 60 is to 45

P = Rs. 1800
R = 8% per annum
{tex} = \frac{1}{4} \times 8\% {/tex} quarterly
= 2% quarterly
n = 1 year
= 4 quarters
{tex}\therefore A = P{\left( {1 + \frac{R}{{100}}} \right)^n}{/tex}
{tex} = 1800{\left( {1 + \frac{2}{{100}}} \right)^4}{/tex}
{tex} = 1800{\left( {1 + \frac{1}{{50}}} \right)^4}{/tex}
{tex} = 1800{\left( {\frac{{51}}{{50}}} \right)^4}{/tex}
{tex} = 1800 \times \frac{{51}}{{50}} \times \frac{{51}}{{50}} \times \frac{{51}}{{50}} \times \frac{{51}}{{50}}{/tex}
= Rs. 1948.38.

Preeti Dabral 3 years ago

S.P. = C.P. – Loss
{tex}\therefore{/tex} 13500 = C.P. – 20% of C.P.
{tex}\therefore{/tex} 13500 = C.P. – {tex}\frac{20}{100} \times{/tex} C.P.
{tex}\therefore{/tex} 13500 = C.P. – {tex}\frac{1}{5} \times{/tex} C.P.
{tex}\therefore{/tex} 13500 = {tex}\left(1-\frac{1}{5}\right){/tex} C.P.
{tex}\therefore{/tex} 13500 = {tex}\frac{4}{5}{/tex} C.P.
{tex}\therefore{/tex} C.P. = {tex}\frac{13500 \times 5}{4}{/tex}
{tex}\therefore{/tex} C.P. = 16875
Hence, she bought it at price Rs. 16875.
