Question

Monthly income of A is 26% more than that of B. Monthly savings of B is same as monthly expenditure of A and monthly savings of A is Rs. 1950 more than monthly expenditure of B. Find the monthly income of A if ratio of monthly expenture of A to B is 8:7??​

Answer 1

monthly income of A =126x=6381

given:

(a) Monthly income of A is 26% more than that of B

the

(b) Monthly savings of B is the same as the monthly expenditure of A and the monthly savings of A is Rs. 1950 more than the monthly expenditure of B

(c) the ratio of monthly expenditure of A to B is 8:7?

to find: monthly income of A

solution:

let the monthly income of B is 100x

So, monthly income of A =126x

let expenditure of A, B =y,z

Compiling equations,

100x=y

126x=1950+z

y/z=8/7             (equation 1)

y=8z/7              (equation 2)

putting the value of y in the top equations.

solving the above equations, we get,

x=1950/38.5

x=50.6

monthly income of A =126x=6381
