6) The number of employees is reduced in the ratio 3: 2 and the salary of each employee are increased in the ratio 4: 5. By doing so, the company saves Rs. 12000. What was the initial expenditure on the salary?
7) The ratio of the salary of A and B, one year ago is 3: 2. The ratio of original salary to the increased salary of A is 2: 3 and that of B is 3: 4. The total present salary of A and B together is Rs. 21500. Find the salary of B.
The initial ratio of A and B is 3: 2
Increased salary of A is 2: 3 that means if it was 2 then it becomes 3.
That means if the old ratio of A: B = 3: 2
8) The ratio of income of two workers A and B are 3: 4. The ratio of expenditure of A and B is 2: 3 and each saves Rs 200. Find the income of A and B.
Let the income of A = 3x, B = 4x
Income- expenditure = saving
Income of A = 3 * 200 = 600
9) The ratio of the expenditure of Pervez, Sunny, and Ashu are 16: 12: 9 respectively and their savings are 20%, 25%, 40% of their income. The sum of the income is Rs 1530, find Sunny's salary.
Let the income of Pervez = x, then the saving = 20x/100
Income - saving = Expenditure
x- 20x/100 = 16
y - 25y/ 100 = 12
z - 40z/ 100 = 9
Now, the ratio of Pervez: Sunny: Ashu = 20: 16: 15 = 51
10) The ratio of income of Pervez, Sunny, and Ashu is 3: 7: 4 and the ratio of their expenditure is 4: 3: 5 respectively. If Pervez saves Rs 300 out of 2400, find the savings of Ashu.
ATQ, income ratio of Pervez: Sunny: Ashu = 3: 7: 4
Saving's of Ashu = Income of Ashu - Expenditure of Ashu
