Question
Ravi had a monthly income of Rs. 32000 and his monthly
expenses were Rs. 25000. In the next year, his income increased by 11% and his expenses rose by 5%. Find the percentage increase in his monthly savings.Solution
ATQ,
Initial savings = 32000 – 25000 = Rs. 7000
New income = 1.11 × 32000 = Rs. 35520
New expenses = 1.05 × 25000 = Rs. 26250
New savings = 35520 – 26250 = Rs. 9270
Percentage increase = [(9270 – 7000)/7000] × 100 = 32.43%
Solve the following equation:
48 ÷ [35 – {30 – (31 – 26 ÷ 2 × 4)}]
