Question

John spends 1/3 of their monthly income on rent , 1/2 on electricity and rest is deposited in savings account. If the amount deposited in savings account is Rs. 4000, what is total monthly income​

Answer 1

Answer:

Total Income = 24000

Step-by-step explanation:

Let john's total income is x

Spend on rent = $\frac{1}{3} x$

Spend on electricity = $\frac{1}{2} x$

Rest is deposited = Rs. 4000

So, ATQ

Spend on rent + Spend on electricity + Deposited = Total Income

$\frac{1}{3} x + \frac{1}{2} x + 4000 = x\\4000 = x - \frac{1}{3} x - \frac{1}{2} x$

$4000 = x - \frac{x}{3} - \frac{x}{2}$

LCM on R.H.S to solve it

$4000 = \frac{6x-2x-3x}{6} \\4000 = \frac{1x}{6}\\4000*6 = x\\24000 = x$
