Combined S.P. = Rs. 20000 × 2 = Rs. 40000
S.P. of one buffalo = Rs. 20000
Gain = 5%
∴ If the S.P. is Rs. 105, then C.P. = Rs. 100
∴ If the S.P. is Rs. 20000, then C.P. = Rs. {tex}\frac{{100}}{{105}} \times 20000{/tex}
{tex} = Rs.\frac{{400000}}{{21}}{/tex}
S.P. of the other buffalo = Rs. 20000
Loss = 10%
∴ If the S.P. is Rs. 90, then C.P. = Rs. 100
∴ If the S. P. is Rs. 20000 = then C.P. {tex} = Rs.\frac{{100}}{{90}} \times 20000 = Rs.\frac{{200000}}{9}{/tex}
∴ Combined C.P. {tex} = Rs.\frac{{400000}}{{21}} + Rs.\frac{{200000}}{9}{/tex}
{tex} = Rs.\frac{{2600000}}{{63}}{/tex}
∴ Overall loss = Combined C.P. – Combined S.P.
{tex} = Rs.\frac{{2600000}}{{63}} - Rs.40000{/tex}
{tex} = Rs.\frac{{80000}}{{63}}{/tex}
= Rs. 1269.87

Total distance=340 Two trains start simuntanously to cross each other( means they will start from opposite directions) Let the speed of train A be-x km/hr Then the speed of train B= X+5 km/hr Distance covered by train A in 2hrs=2x km Train B in 2 hrs=(x+5)x2=2x+10 km Distance left to cross eachother=30km Therefore, 340-(2x+10+2x)=30 X=75 Speed=trainA=75km/hr TrainB=75+5=80km/hr

Sia ? 6 years, 5 months ago

Let the measure be {tex}{x^0}{/tex}
Then its supplement is {tex}{180^0} - {x^0}{/tex}
According to the question
{tex}{x^0} = 2\left( {{{180}^0} - {x^0}} \right){/tex}
{tex}{x^0} = {360^0} - 2{x^0}{/tex}
{tex}3x = {360^0}{/tex}
{tex}x{\text{ }} = {120^0}{/tex}

Therfore the other angle is {tex}180^\circ - 120^\circ = 60^\circ{/tex}
The measure of the angles are {tex}{120^0} {/tex} and {tex}{60^0}{/tex}respectively.
