SHUBHAM SATYARTHE (Question: 181766.0 )

SIR PLEASE GIVE IN SHORT FORM SOLUTION

Question:

The ratio of income in two consecutive years is 2 : 3 respectively. The ratio of their expenditure is 5 : 9. Income of second year is Rs. 45000 and Expenditure of 1st year is Rs. 25000. Savings in both years together is?

Options:
A) Rs. 4000   
B) Rs. 5000   
C) Rs. 6000   
D) Rs. 7000
Solution:

Income of 2nd year = 3x =  45000

x = 45000 ÷ 3 = 15000

Income of 1st year = 2x

= 2 × 15000 = 30000

Expenditure of 1st year = 5y = 25000

y = 25000 ÷ 5 = 5000

Expenditure of 2nd year = 9y = 45000

Total savings =  [Total income - total expenditure]

= 45000 + 30000 - (25000 + 45000)

= 75000 - 70000 = 5000
