Answer 1

Answer:

$\sf{\circ\;Total\;amount\;spend\;by\;Mrs.\;Khosla\;was\;Rs.\;91\dfrac{1}{2}.}$

Step-by-step explanation:

Given that:

• Mrs. Khosla purchased 2 1/2 kg of mangoes at the rate of ₹25 3/4 per kg.

• She also bought 1 3/4 kg of grapes at the rate of ₹15 1/2 per kg.

To Find:

• Total money spent by Mrs Khosla.

Solution:

Finding total money spent in total:

$\sf{Rate\;of\;mangoes \;per\; kg=25\dfrac{3}{4}=Rs.\;\dfrac{103}{4}}$

$\sf{Amount\;of\;mangoes\;purchased=2\dfrac{1}{2}=\dfrac{5}{2}\;kg}$

$\bf{Amount\;spent\;on\;mangoes=Rs.\left(\dfrac{5}{2}\times\dfrac{103}{4}\right)}$

$\sf{Rate\;of\;grapes\;per\; kg=15\dfrac{1}{2}=Rs.\;\dfrac{31}{2}}$

$\sf{Amount\;of\;mangoes\;purchased=1\dfrac{3}{4}=\dfrac{7}{4}\;kg}$

$\bf{Amount\;spent\;on\;grapes=Rs.\left(\dfrac{7}{4}\times\dfrac{31}{2}\right)}$

--------------------------------------

$\sf{Amount\;apent\;altogether=\left(\dfrac{7}{4}\times\dfrac{31}{2}\right)+\left(\dfrac{5}{2}\times\dfrac{103}{4}\right)}$

$\sf{=\dfrac{217}{8}+\dfrac{515}{8}}$

$\sf{=\dfrac{732}{8}}$

$\sf{=91\dfrac{4}{8}}$

$\sf{=91\dfrac{1}{2}}$

Hence,

$\sf{\circ\;Total\;amount\;spend\;was\;}\bf{Rs.\;91\dfrac{1}{2}.}$
