Question
Person X's earnings exceed Person Y's by 25%, and both
individuals manage to save Rs. 2400 each. The ratio of Person Y's expenses to Person X's expenses is 12:17. Can you determine the income of Person Y?Solution
ATQ, Let the income of Y be Rs.a Income of X = Rs. a × 125% (a – 2400)/(a × 1.25 – 2400) = 12:17 17a – 40800 = 15a – 28800 40800 – 28800 = 17a – 15a 2a = 12000 a = 6000
