Question

Total salary of a and b is 1500 a spend 90% while b spends 80% of his salary if ratio of their savings is 3 ratio 4 then what is the salary of a and b

Answer 1

Answer:

Salary of : a = 900   b= 600

Step-by-step explanation:

Since we don't know the salary of both a and b;

Let us take the salary of a = x;

Hence according to the statement given in the question,

Sum of salary's of a and b = 1500

Thus, let  b=1500-x;

Now the expenditure of a = 90% of x

Hence, savings of a = 10% of x

Similarly, expenditure of b = 80% of (1500-x)

Hence, savings of b = 20% of (1500-x)

Given, the ratio of savings of a and b = 3/4

Therefore, (10% of x) / (20% of (1500-x) ) = 3/4

Solving, we get x = 900.

Therefore salary of a = x =900

Thence, salary of b = 1500-x = 1500-900= 600.
