Answer 1

Given :- The ratio of expenditure of A,B and C are 16:12:9 respectively and their savings are 20%, 25% and 40% of their income. If the sum of their income is Rs.15300, Find B's salary. ?

Solution :-

Let us assume that, expenditure of A, B and C are 16x , 12x and 9x respectively .

since their savings are 20% , 25% and 40% of their income . so, they must spend 80%, 75% and 60% each .

then,

→ 16x of A's income = 80%

→ A's income = (16/80) * 100 = 20x

and,

→ 12x of B's income = 75%

→ B's income = (12/75) * 100 = 16x

and,

→ 9x of C's income = 60%

→ C's income = (9/60) * 100 = 15x

therefore,

→ A's income + B's income + C's income = Total income

→ 20x + 16x + 15x = 15300

→ 51x = 15300

→ x = 15300/51

→ x = 300

hence,

→ Salary of B = 16x = 16 * 300 = Rs.4800 (Ans.)
