The ratio of income of Jitendra, and Narendra is 4 : 7 and the ratio of their expenditure is 6 : 5 respectively. If Jitendra saves Rs..400 out of Rs.2,800 income, then find the savings of Narendra.
Answer & explanation
Correct answer: option 1
Jitendra : Narendra
Income 4 : 7
Expenditure 6 : 5
____________________________
Income of Jitendra = 2,800 = 4R
1R = 700
∴ Income of Narendra = 7R = 7 x 700 = 4,900
Savings of Jitendra = 400, Expenditure = 2800 - 400 = 2400 = 6a
1a = 400
∴ Expenditure of Narendra = 5a = 5 x 400 = 2000
Therefore, Saving of Narendra = 4900 - 2000 = 2,900
