Rahim spends 60% of his salary on rent,EMI &miscellaneous expenses in the ratio of 2:1:3,if he spends a total of 16050 on rent & EMItogether, how much his monthly salary.

Answer»

Let total salary be x

Let he spend on rent = 2yLet he spend on EMI = yLet he spend on Other expenses = 3y

As per given condition2y + y = 106503y = 10650y = 10650/3 = 3550

Now,Total expenses = (2y + y + 3y)= 6y

Then, 6y = (60/100)*x6*3550 = (60/100)*xx = 355*100 = 35500

Therefore,Rahim monthly salary = Rs 35500

works.Example 11 The ratio of incomes of two persons is 9: 7 and the ratio of theitexpenditures is 4 : 3. If each of them manages to save 2000 per month, find theirmonthly incomes.

Answer»

Denote the incomes of the two person by 9x and 7x and their expenditures by 4y and 3y respectively.

Then the equations formed in the situation is given by:

9x – 4y = 2000 ... (1)

7x – 3y = 2000 ... (2)

Step 1: Multiply Equation (1) by 3 and Equation (2) by 4 to make the coefficients ofy equal. Then you get the equations:

27x – 12y = 6000 ... (3)

28x – 12y = 8000 ... (4)

Step 2: Subtract Equation (3) from Equation (4) to eliminate y, because the coefficients of y are the same. So,you get

(28x – 27x) – (12y – 12y) = 8000 – 6000

x = 2000

Step 3: Substituting this value of x in (1),

9(2000) – 4y = 2000

y = 4000

The solution of the equations is x = 2000, y = 4000.

Therefore, the monthly incomesof the persons are Rs. 18,000 and Rs. 14,000, respectively.

The ratio of incomes of two persons is 9:7 and the ratio of their expenditures is 4:3,Ieach of them manages to save 2000 per month, find their monthly income

Answer»

Let their salaries be 9x and 7xlet their expenditure be 4y and 3yso,ATQ9x-4y=2000—(1)7x-3y=2000—(2)so,from (1)x=(2000+4y)/9—(3)put x in (2)7[(2000+4y)/9]-3y=2000(14000+28y)/9-3y=2000(14000+28y-27y)/9=2000y+14000=18000y=4000

now put y in (3)x=(2000+4×4000)/9x=(2000+16000)/9x=18000/9x=2000

so,salary of first person=9×2000=Rs.18000 salary of second person=7×2000=Rs.14000

9.600 more than his wife.A man earnsOne-tenth of man's salary and one-sixthof the wife's salary amount to 1500.which is saved every month. Find theirtotal monthly expenditures,

Answer»

Let salary of wife be x.Thus, salary of man = x+600.

According to question,

(x+600/10) + (x/6) = 1500

(3*(x+600)/10*3) + (5*x/6*5) = 1500

(3x+1800/30) + (5x/30) = 1500

3x + 1800 + 5x = 1500*30

8x + 1800 = 45000

8x = 45000 - 1800

8x = 43200

x = 43200/8

x = 5400

Thus, salary of wife = 5400 and salary of man = 5400 + 600 = 6000.
