Answer:

⚘Question:

The monthly pocket money of Ravi and Sanjeev are in the ratio 5:7 their expenditure ratio is 9:13.If each saves rupees 40.Find their pocket money.

\sf\tt\large{\red {\underline {\underline{⚘\;Answer:}}}}⚘Answer:

The monthly pocket money of Ravi =$400

The monthly pocket money of Sanjeev =$560.

\sf\tt\large{\blue {\underline {\underline{⚘\;Given: }}}}⚘Given:

The monthly pocket money of Ravi and Sanjeev are in ratio 5:7 their expenditure ratio is 9:13.If each saves $40.

\sf\tt\large{\red {\underline {\underline{⚘\;To find:}}}}⚘Tofind:

Here we should find the pocket money of Ravi and Sanjeev.

\sf\tt\large{\green {\underline {\underline{⚘\;Solution:}}}}⚘Solution:

\sf\tt\large{\green {\underline {\underline{⚘\;Consider:}}}}⚘Consider:

\sf\tt\large{\red {\underline {\underline{⚘\;Case (i):}}}}⚘Case(i):

In the case of Ravi .

If we want to get the answer to this question we should convert the given question clues into a equation.Then we can solve.

Here,

Money savings =$40,Monthly pocket money =5m,Monthly expenditure is =9n

Then, here we get the equation that is

5m - 9n = 405m−9n=40

\sf\tt\large{\green {\underline {\underline{⚘\;Case (ii):}}}}⚘Case(ii):

In the case of Sanjeev

Money savings =$40,Monthly pocket money =7m,Monthly expenditure =13n

Then we get the equation that is,

7m - 13n = 407m−13n=40

Let,

Here we should change something else that is we should multiply the equation i in 7 and equation (ii) in 5

Then we get that,

35m - 63n = 280 - - - - (i)35m−63n=280−−−−(i)

35m - 65n =200 - - - - (ii)35m−65n=200−−−−(ii)

Now,

By subtracting two equations we get that,

+ 2n = 80+2n=80

n = \frac{80}{2} = 40n=280=40

Now,

Putting the value of n in equation 2 we get that,

7m - 13n = 407m−13n=40

7m-13 (40)=40

7m-520=40

7m=40+520

7m=560

m=560/7

m=80.

\sf\tt\large{\red {\underline {\underline{⚘\;Therefore:}}}}⚘Therefore:

Monthly pocket money of Ravi =5m=5×80=$400

Monthly pocket money of Sanjeev =7m=7×80=$560.
