Question

A and b hv monthly income in the ratio of 5:6 and monthly expenditure in the ratio of 3:4 if they save 1800 and 1600 find the monthly income of b

Answer 1

$\huge \mathfrak {Answer:-}$

Incomes of $A\:and\:B$:

$5x$ and $6x$

Expenses of $A\:and\:B$:

$3y$ and $4y$

Now,

Savings of $A = 5x - 3y = 1800---(1)$

Savings of $B = 6x - 4y = 1600---(2)$

By solving both the equations (1) and (2),

We get,

$y = 1400$

Now,

Monthly income of B = Expenses of B + Savings of B

$= 4y + 1600$

$= 4(1400) + 1600$

$= 5600 + 1600$

$= 7200$

Therefore,

Monthly income of B $= Rs. 7200$

Answer 2

Given : Incomes of A and B

=== > 5x5x and 6x6x

Expenses of A and B

====> 3y3y and 4y4y

Given,

Savings of A = 5x - 3y = 1800---(1)

A=5x−3y=1800****(1)

Savings of B = 6x - 4y = 1600---(2)

B=6x−4y=1600****(2)

On Solving Both The Equations (1) And (2),

y = 1400

M.I of B = Expenses of B + Savings of B

=4y+1600
​
=4(1400)+1600
​= 5600 + 1600
​= 7200

Therefore,

Monthly income of B = Rs. 7200
