The monthly income of Raju was Rs. 13500 and his monthly
expenditure was Rs. 9000. Next year his income increased by 17% and his expenditure increased by 7%. The percent increase in his savings is:Solution
ATQ,
Monthly savings of Raju initially = 13500 – 9000 = Rs. 4500
Increased monthly income = 1.17 × 13500 = Rs. 15795
Increased monthly expenditure = 1.07 × 9000 = Rs. 9630
Increased monthly savings = 15795 – 9630 = Rs. 6165
Percentage increase = [(6165 – 4500)/4500] × 100 = 37%
