The incomes of A,B and C are in the ratio 3:7:4 and their expenses in ...
Given:
Incomes ratio of A, B and C = 3:7:4
Expenses ratio of A, B and C = 4:3:5
A's saving = Rs 300
A's income = Rs 2,400

Calculations:
1. Find A's expenses:
A's saving = A's income - A's expenses
Rs 300 = Rs 2,400 - A's expenses
A's expenses = Rs 2,400 - Rs 300 = Rs 2,100
2. Find the savings of B and C:
Let the incomes of B and C be 7x and 4x respectively.
Expenses of B and C will be 3y and 5y respectively.
3. Calculate the value of x and y:
Given, A's expenses = 4x, B's expenses = 3y, C's expenses = 5y
4x = Rs 2,100
x = Rs 2,100 / 4
x = Rs 525
3y = Rs 2,400 - Rs 300
3y = Rs 2,100
y = Rs 2,100 / 3
y = Rs 700
4. Calculate the savings of B and C:
Savings of B = 7x - 3y
Savings of B = 7(Rs 525) - 3(Rs 700)
Savings of B = Rs 3,675
Savings of C = 4x - 5y
Savings of C = 4(Rs 525) - 5(Rs 700)
Savings of C = Rs 2,100

Conclusion:
Therefore, the savings of B and C are Rs 3,675 and Rs 2,100 respectively. So, option A is the correct answer.

The incomes of A,B and C are in the ratio 3:7:4 and their expenses in ...
Given income of A is 2400 so
3x(from income ratio)=2400
x=800 hence simultaneously incomes of b and c are 5600 and 3200
savings of A=300 so expenditure is 2400-300=2100
so from second ratio 4x=2100
x=525 simultaneously expenditure of b and c are 1575 and 2625
substraction of income - expenditure is savings so
b=5600-1575=4025
c=3200-2625=575
